…4311 trivy-fs on PR #784 surfaced three new MEDIUM findings against the locked pypdf 6.15.0 artifact, all availability risks directly on NewsDOM's untrusted PDF-upload path: - CVE-2026-84309: a crafted cyclic /Next outline tree drives TreeObject.insert_child into an infinite loop. - CVE-2026-84310: _get_outline traversal has no entry-count or nesting-depth limit, allowing long runtimes / large memory use. - CVE-2026-84311: a reused-XObject form graph without a visited guard produces exponentially many text-extraction traversal paths. All three are fixed upstream in pypdf 6.16.0/6.16.1. Raised the direct floor to >=6.16.1,<7.0 (lock resolves 6.16.2, current latest) rather than suppressing the findings, per this repo's remediate-at-the-base convention so every open PR inherits the fix. Updated the paired contract tests (test_pypdf_security_floor.py, test_project_metadata.py) and the dependency-security-baseline doctoring record with the new CVE citations. Verified: full suite 483 passed / 100% coverage, pip-audit 0 vulnerabilities, local trivy fs scan 0 vulnerabilities. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

@jules Exact-head hosted evidence is now a real RED, not a queue wait. On Repair this same branch by a normal descendant after re-reading the live head/intervening delta. Minimal GREEN: make the current security changelog entry name the declared requirement as one exact code token |
…l Markdown `test_current_pypdf_advisories_and_floor_are_documented` asserted a fused `pypdf>=6.16.1,<7.0` code span, but CHANGELOG.md writes the package and its specifier as separate inline-code spans, and it compared a single-line provenance sentence against a paragraph that Markdown wraps across two lines in docs/doctoring/dependency-security-baseline.md, so the test failed on this branch. The CHANGELOG check now requires one entry line naming `pypdf`, the specifier and the release the lock resolved; the provenance check compares whitespace-normalized text. Every version literal in the module now derives from _REQUIRED_PYPDF_VERSION and the lock file, so a future floor bump has one place to change and the documentation checks cannot keep matching a superseded floor. Negative controls: the test fails when the CHANGELOG floor or the provenance release is set back to the previous values. Addresses the CodeRabbit and Devin review comments on #794.

Security objective
Remediate three newly surfaced pypdf availability findings on NewsDOM's untrusted PDF-ingestion path by raising the direct dependency floor instead of suppressing scanner evidence.
pypdf>=6.16.1,<7.0The repository keeps the findings visible to Trivy and raises the source requirement and generated lock together. The change does not claim that a dependency bump replaces upload bounds, parser timeouts, process/container isolation, concurrency controls, or malformed-PDF resilience testing.
Review RED → GREEN
Fresh review found two valid evidence defects in the original dependency commit
fb04c1993fbee285c5a926def566e76ddb335a64:test_current_pypdf_advisories_and_floor_are_documentedstill accepted the historicalpypdf>=6.15.0,<7.0changelog text, so deletion of the new 6.16.1 floor could escape the contract.docs/doctoring/dependency-security-baseline.mddescribed the active lock as 6.16.2 but its provenance sentence still said PyPI metadata and lock hashes confirmed 6.15.0.RED
e22189ae25097762b485b11749ed2962a0c1febastrengthens the executable contract to require the currentpypdf>=6.16.1,<7.0changelog floor and the current 6.16.2 provenance sentence in addition to all three CVE references and the no-suppression invariant. Against the predecessor documentation, that provenance assertion is intentionally RED.GREEN
4ecca54ebe2df35612f1b1125e39ad65236a8decupdates only the stale current-provenance statement to 6.16.2 while preserving the historical 6.15.0 remediation record. Both Devin review threads are resolved against this exact lineage.PyPI lists 6.16.2 as the latest pypdf release, published 2026-08-23, and its published sdist/wheel SHA-256 values match the hashes recorded in this branch's
