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-xq8g-hgh6-87hv 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 377,636 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
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.

BlueBubbles Webhook Missing Guess Rate Limiting Enables Brute-Force Guessing of Weak Webhook Password
Affected Packages / Versions

openclaw - Affected versions:
<= 2026.3.24 - First patched version:
2026.3.25 - Latest published npm version at verification time:
2026.3.24
Details
BlueBubbles webhook auth previously rejected wrong passwords without throttling repeated guesses, allowing brute-force attempts against weak webhook passwords. Commit 5e08ce36d522a1c96df2bfe88e39303ae2643d92 adds repeated-guess throttling before auth failure responses.
Verified vulnerable on tag v2026.3.24 and fixed on main by commit 5e08ce36d522a1c96df2bfe88e39303ae2643d92.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of openclaw has shipped for GHSA-xq8g-hgh6-87hv yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-xq8g-hgh6-87hv can be triaged on real exposure rather than presence alone.
Tailored to GHSA-xq8g-hgh6-87hv. 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-xq8g-hgh6-87hv in your dependencies?
O3 Security finds GHSA-xq8g-hgh6-87hv across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
