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-4p4w-6hg8-63wx 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 379,842 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, a proxy for how much of the ecosystem is exposed.
angular-sanitizenpmDescription
Improper sanitization of the value of the 'href' and 'xlink:href' attributes in '<image>' SVG elements in AngularJS's 'ngSanitize' module allows attackers to bypass common image source restrictions. This can lead to a form of Content Spoofing https://owasp.org/www-community/attacks/Content_Spoofing and also negatively affect the application's performance and behavior by using too large or slow-to-load images.
This issue affects AngularJS versions greater than or equal to 1.3.1.
Note: The AngularJS project is End-of-Life and will not receive any updates to address this issue. For more information see here https://docs.angularjs.org/misc/version-support-status .

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for angular-sanitize, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of angular-sanitize has shipped for GHSA-4p4w-6hg8-63wx 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
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-4p4w-6hg8-63wx can be triaged on real exposure rather than presence alone.
Tailored to GHSA-4p4w-6hg8-63wx. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Frequently Asked Questions
Is GHSA-4p4w-6hg8-63wx in your dependencies?
O3 Security finds GHSA-4p4w-6hg8-63wx across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
