Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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
CVE-2025-53624 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 377,238 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.
docusaurus-plugin-content-gistsnpmDescription
The Docusaurus gists plugin adds a page to your Docusaurus instance, displaying all public gists of a GitHub user. docusaurus-plugin-content-gists versions prior to 4.0.0 are vulnerable to exposing GitHub Personal Access Tokens in production build artifacts when passed through plugin configuration options. The token, intended for build-time API access only, is inadvertently included in client-side JavaScript bundles, making it accessible to anyone who can view the website's source code. This vulnerability is fixed in 4.0.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for docusaurus-plugin-content-gists, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update docusaurus-plugin-content-gists to 4.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-53624 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 CVE-2025-53624 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-53624. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
How to detect CVE-2025-53624
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
nuclei -id cve-2025-53624 -u https://target- Template
- Docusaurus Gists Plugin < 4.0.0 - GitHub Personal Access Token Exposure
- Severity
- high
- Impact
- A GitHub personal access token exposure vulnerability can grant an attacker unauthorized access to your repositories and organization resources, potentially leading to data exfiltration, code injection, and supply chain attacks.
- Remediation
- Update docusaurus-plugin-content-gists to version 4.0.0+. Revoke access to the GitHub PAT that was used: https://github.com/settings/tokens.
