Thanks for picking this up — CVE-2025-58367 is one of the few criticals in our Dependabot backlog, so the fix is welcome. A few things to resolve before merge.

Verified locally (macOS, Python 3.12): uv lock --check consistent (369 packages), uv sync --extra dev clean, uv run pytest tests/ -q → 53 passed.

1. The constraint resolves to 9.1.0, not 8.6.1.

The title says "upgrade deepdiff to 8.6.1", but >=8.6.1 is a floor rather than a pin, and the lockfile resolves to 9.1.0 — a major-version bump. It also pulls in a new transitive dependency, cachebox==5.2.3 (a Rust-backed cache), which wasn't previously in the tree:

- deepdiff==8.1.1
+ deepdiff==9.1.0
+ cachebox==5.2.3

2. deepdiff is load-bearing for the vendored AgentDojo suites.

It has no direct imports under guardrail/ or the top-level scripts, but the vendored benchmark uses it for utility checks:

benchmark/agentdojo/benchmarks/agentdojo/default_suites/v1/workspace/task_suite.py:
    from deepdiff import DeepDiff
    WorkspaceDeepDiff = partial(DeepDiff, exclude_paths=..., exclude_regex_paths=...)
benchmark/agentdojo/benchmarks/agentdojo/default_suites/v1/travel/task_suite.py:
    from deepdiff import DeepDiff

These comparisons decide whether a task's environment changed, i.e. they feed benchmark pass/fail. A major-version change in comparison or exclude_paths semantics could shift AgentDojo results silently. Detection/tests/ doesn't exercise the AgentDojo suites, so the passing test run above doesn't cover this.

3. It changes an intentional exact pin.

deepdiff==8.1.1 was one of 22 == pins in pyproject.toml. Per the Detection README, those exist for benchmark reproducibility against the paper's evaluation. Switching to >= means a later uv lock regeneration can drift without review, on a package that feeds AgentDojo ground-truth comparisons.

---

Requested change — one line, keeps everything else as-is:

- "deepdiff>=8.6.1",
+ "deepdiff==8.6.1",

8.6.1 is the patched version per the advisory, so this still closes the CVE while preserving the pinning convention, avoiding the 9.x major bump, and likely avoiding the new cachebox dependency. Please regenerate uv.lock after the change.

If you'd prefer to take 9.1.0 deliberately, that's fine too, but it should be pinned as ==9.1.0 and accompanied by an AgentDojo run confirming the diff semantics are unchanged.

Re-posting as a plain comment instead — this is feedback, not a merge block.

[anupamme]

Hello, saw that it was only feedback not a merge block, so I addressed the issues anyway. Let me know if anything is still missing.

[pengyuzhang]

Blocking: the regenerated lockfile carries two silent downgrades that revert already-merged security fixes.

Diffing the base and head lockfiles package-by-package (359 packages each), three versions changed — one intended, two not:

Package	main	this PR
deepdiff	8.1.1	8.6.1	intended ✅
jupyter-server	2.20.0	2.16.0	downgrade ❌
pyjwt	2.13.0	2.10.1	downgrade ❌

These aren't merge-staleness artifacts — the merge base is current main HEAD (7d7faf9), zero commits behind.

Tracing the history:

• jupyter-server 2.20.0 → 2.16.0 directly reverts merged PR fix: upgrade jupyter-server to 2.20.0 (CVE-2026-44727) #24 (9b2546d, same automation, "fix: CVE-2026-44727"). CVE-2026-44727 resolves to GHSA-fcw5-x6j4-ccmp — Jupyter Server: Stored XSS in NbconvertFileHandler / NbconvertPostHandler — which this PR puts straight back. Merging this undoes fix: upgrade jupyter-server to 2.20.0 (CVE-2026-44727) #24.
• pyjwt 2.13.0 → 2.10.1 reverts merged PR chore(deps): bump pyjwt from 2.10.1 to 2.13.0 in /Detection #15 (0086cf2, "chore(deps): bump pyjwt from 2.10.1 to 2.13.0").

Per OSV, the two downgrades reintroduce 11 advisories in order to remove 1. All 11 are currently fixed on main:

pyjwt 2.10.1 (6 reintroduced, 0 remaining in 2.13.0):

• GHSA-jq35-7prp-9v3f — algorithm allow-list bypass when decoding with PyJWK/PyJWKClient keys
• GHSA-xgmm-8j9v-c9wx — public-key JWK accepted as HMAC secret → forged HS256 tokens
• GHSA-993g-76c3-p5m4 — PyJWKClient missing scheme allowlist → SSRF + token forgery
• GHSA-752w-5fwx-jx9f — unknown crit header extensions accepted
• GHSA-fhv5-28vv-h8m8 — unbounded JWKS requests via attacker-controlled kid (DoS)
• GHSA-w7vc-732c-9m39 — unauthenticated DoS via unbounded Base64URL decoding

jupyter-server 2.16.0 (5 reintroduced, 0 remaining in 2.20.0):

• GHSA-fcw5-x6j4-ccmp (= CVE-2026-44727, the one fix: upgrade jupyter-server to 2.20.0 (CVE-2026-44727) #24 just fixed) — stored XSS
• GHSA-5789-5fc7-67v3 — path traversal via incorrect startswith() root-directory check
• GHSA-24qx-w28j-9m6p — CORS origin validation bypass via re.match() in allow_origin_pat
• GHSA-5mrq-x3x5-8v8f — auth cookies remain valid after password reset
• GHSA-qh7q-6qm3-653w — open redirect in the next query parameter

Both packages are transitive (pyjwt ← msal ← azure-identity; jupyter-server ← jupyterlab/notebook via the notebook extra), which lowers the impact but doesn't erase it — and makes it exactly the kind of regression that goes unnoticed until the next scan.

Blocking: uv.lock was regenerated by an older uv than the project uses.

The lockfile header goes revision = 3 → revision = 1, and every upload-time = "..." attribute is stripped from all ~359 package entries. That accounts for essentially the entire +2651/−2651 churn — the real change is two lines.

main has been on revision 3 since the initial public release, so this is a lockfile format downgrade, not an update. The stale resolver is also the most likely cause of the pyjwt and jupyter-server downgrades noted above.

Practical consequence: the next person to run uv lock on a current uv will regenerate revision 3 with upload-time restored, producing another ~2600-line diff.

Suggested fix for both issues: regenerate with a current uv, scoped to the one package —

uv lock --upgrade-package deepdiff

That moves only deepdiff, leaves the other 358 entries byte-identical, and preserves revision = 3 + upload-time. The PR then becomes a ~10-line reviewable diff.

Two things worth flagging about detectability:

• uv lock --check passes on the current head, so tooling won't catch this. The lock is internally consistent with pyproject.toml; it just pins worse versions.
• CI runs uv sync --extra dev without --locked/--frozen, so a drifting or regressed lockfile can't fail the build either. Adding --locked to the Detection and Sensor jobs in ci.yml would make this class of regression visible mechanically — worth doing separately, since this automation will keep producing these PRs.

[anupamme]

Addressed review comments. Pls review.

[pengyuzhang]

Thanks for the quick turnaround — the pin is exactly right now.

Confirmed good: deepdiff==8.6.1 keeps the exact-pin convention, and a package-set comparison of this lock against main shows the change is fully contained:

packages only in PR lock:   []
packages only in main lock: []
version changes:            {'deepdiff': ('8.1.1', '8.6.1')}

One package moved, nothing added or removed — so the 9.x major bump and the new cachebox dependency are both gone, and the AgentDojo DeepDiff usage now only sees a patch-level change within 8.x. uv lock --check passes (368 packages resolved).

One thing to fix before merge: the lockfile lost 76 environment markers.

The diff is 164 lines touching packages unrelated to deepdiff (nvidia-*, numpy, torch, semgrep, glom, …), all of this shape:

- { name = "numpy", version = "1.26.4", ..., marker = "python_full_version < '3.12'" },
+ { name = "numpy", version = "1.26.4", ... },

Marker counts: main has 202, this branch has 126.

I checked whether that's just a uv-version difference, and it isn't:

lockfile	marker = count
main as-is	202
main regenerated with uv 0.12.1	202
fresh rm uv.lock && uv lock from this branch's pyproject	176
this branch's submitted lock	126

So the submitted lock doesn't match what uv produces from the same inputs — something dropped conditional markers (older uv, a different tool, or a manual edit). The practical concern is that entries like the CUDA nvidia-* packages lose their sys_platform == 'linux' guards, so a macOS/ARM install could pull wheels it previously skipped. The resolved package set is unchanged, so this is about install-time conditionals rather than the dependency graph — but it's unnecessary risk to carry in a security patch.

Requested: regenerate the lock cleanly on top of the deepdiff==8.6.1 pyproject —

cd Detection && rm uv.lock && uv lock

That should shrink the diff to just the deepdiff block and preserve the markers. Once the lock diff is contained, this is good to merge — happy to re-check straight away.

[anupamme]

addressed. pls review.

[pengyuzhang]

My apologies — my previous comment gave you bad advice, and it made this revision worse than the one before it. Two corrections.

1. My marker analysis was wrong, and the previous revision (11e080f) was already correct.

I claimed the 76 dropped marker = entries weren't a uv artifact, based on regenerating main's lock and seeing all 202 markers preserved. That test was invalid: I ran uv lock without changing pyproject.toml, so uv had nothing to do and left the file untouched.

Doing it properly — start from main's lock, apply only the deepdiff==8.6.1 edit, then uv lock:

packages: 368    markers: 126    lock diff: 164 lines (82+/82-)

That is exactly what 11e080f contained. The marker normalization is simply what uv 0.12.1 emits when it rewrites those entries. There was nothing wrong with your lockfile — I was chasing a non-issue.

2. rm uv.lock && uv lock was the wrong command, and I shouldn't have suggested it.

It re-resolves everything from scratch, so every non-pinned dependency floats to latest. This revision's effect:

	main	this revision
packages	368	380
torch	2.7.1	2.13.0
CUDA stack	nvidia-*-cu12	cu13 (entire stack swapped)
openai	1.100.2	1.109.1
cryptography	45.0.5	45.0.7 + 50.0.0
version changes	—	~180 packages
new packages	—	opencv-python, scikit-learn, scipy, onnxruntime, magika, pdfplumber, …

5,747 changed lines. For this repo that's a problem beyond noise: Detection/README.md pins exact versions for benchmark reproducibility against the paper's evaluation, and the llamafirewall 0.0.0 local editable entry — the baseline behind Table 2 — is no longer in the lock.

To fix — restore the incremental lock:

cd Detection
git checkout main -- uv.lock     # discard the full re-resolve
# pyproject.toml already has deepdiff==8.6.1
uv lock                           # incremental; touches only what must change

uv lock --upgrade-package deepdiff works equally well. Either produces the 164-line diff with no torch/CUDA churn.

Sorry for the round trip — the pin itself has been right since 11e080f, and once the lock is back to the incremental form this is good to merge.

[anupamme]

addressed. pls review.

[pengyuzhang]

Approving — this is exactly right now, and thanks for bearing with the round trip caused by my earlier bad advice.

Verified locally (macOS, Python 3.12, uv 0.12.1):

check	result
pyproject.toml diff	one line, deepdiff==8.1.1 → ==8.6.1 (exact pin preserved)
lock diff	164 lines (83+/83−)
package count	368, unchanged from main
packages added / removed	none / none
version changes	{'deepdiff': ('8.1.1', '8.6.1')} — one, only
llamafirewall entries	3, intact (Table 2 baseline)
torch / CUDA stack	untouched (2.7.1, cu12)
uv lock --check	368 packages resolved
uv sync --extra dev	clean swap to 8.6.1
uv run pytest tests/ -q	53 passed

The strongest check: I regenerated the lock independently — git checkout main -- uv.lock, apply only the pyproject edit, uv lock — and the result is byte-for-byte identical to the file in this PR (diff -q clean). No hand-editing, no stray resolution; it's precisely what the tooling produces from these inputs. That also confirms the 126-vs-202 marker = count is uv 0.12.1's normalization, as I retracted earlier.

Closes CVE-2025-58367 (critical: DeepDiff class pollution → DoS/RCE), one of the four distinct criticals in our Dependabot backlog. Patch-level within 8.x, so the vendored AgentDojo suites' DeepDiff comparison semantics are unaffected.
