GHSA-q29v-xc37-wh5m
HIGHGHSA-q29v-xc37-wh5m is a high-severity (CVSS 7.1) CWE-73 vulnerability in docling. O3 Security confirms whether GHSA-q29v-xc37-wh5m is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-q29v-xc37-wh5m plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 358,265 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
doclingReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Impact
The HTML backend did not perform sufficient validation during resource handling:
- Accepted
file://URIs enabling local file system access whenenable_local_fetch=True - Path resolution allowed traversal outside intended directories via
../sequences and absolute paths - Did not block internal network resources under
enable_remote_fetch=True - HTTP redirects were not validated, potentially redirecting to unintended schemes
- No resource limits for remote image downloads and
data:URIs
Patches
Fixed in versions 2.91.0 (initial fixes) and 2.94.0 (additional improvements). The fixes implement:
- Updated local path treatment: absolute files always blocked, relative paths require
enable_local_fetch=True(default: False) and containment within configuredbase_pathfor path traversal protection file://scheme stripped & treated as local path (above)- IP address validation to prevent SSRF
- HTTP redirect validation, connection and read timeouts
- Size limit for both remote images (with streaming download) and base64-decoded data URIs
Workarounds
Keep both enable_local_fetch=False and enable_remote_fetch=False (defaults) when processing untrusted HTML documents.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for docling. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update docling to 2.94.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q29v-xc37-wh5m is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-q29v-xc37-wh5m is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-q29v-xc37-wh5m. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-q29v-xc37-wh5m in your dependencies?
O3 detects GHSA-q29v-xc37-wh5m across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
