Exploitation Status
No confirmed exploitation observed yet
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for GHSA-q76q-q8hw-hmpw.
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-q76q-q8hw-hmpw 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 377,166 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
Impact
Harbor fails to validate the user permissions when reading job execution logs through the P2P preheat execution logs - API call
GET /projects/{project_name}/preheat/policies/{preheat_policy_name}/executions/{execution_id}/tasks/{task_id}/logs
By sending a request that attempts to read P2P preheat execution logs and specifying different job ids, malicious authenticatedusers could read all the job logs stored in the Harbor database.
Patches
This and similar issues are fixed in Harbor v2.5.2 and later. Please upgrade as soon as possible.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/goharbor/harbor, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/goharbor/harbor to 1.10.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q76q-q8hw-hmpw 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-q76q-q8hw-hmpw can be triaged on real exposure rather than presence alone.
Tailored to GHSA-q76q-q8hw-hmpw. 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-q76q-q8hw-hmpw in your dependencies?
O3 Security finds GHSA-q76q-q8hw-hmpw across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
