docconv OS Command Injection vulnerability
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-6m4h-hfpp-x8cx 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 377,333 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.

Description
A vulnerability was found in docconv prior to version 1.2.1. It has been declared as critical. This vulnerability affects the function ConvertPDFImages of the file pdf_ocr.go. The manipulation of the argument path leads to os command injection. The attack can be initiated remotely. Upgrading to version 1.2.1 can address this issue. The name of the patch is b19021ade3d0b71c89d35cb00eb9e589a121faa5. It is recommended to upgrade the affected component. VDB-216502 is the identifier assigned to this vulnerability.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/sajari/docconv, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/sajari/docconv to 1.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6m4h-hfpp-x8cx 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-6m4h-hfpp-x8cx can be triaged on real exposure rather than presence alone.
Tailored to GHSA-6m4h-hfpp-x8cx. 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-6m4h-hfpp-x8cx in your dependencies?
O3 Security finds GHSA-6m4h-hfpp-x8cx across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
