CVE-2024-41656Network attack vector

Stored XSS via HTML-formatted external-issue annotations

Published Jul 23, 2024 · Updated Aug 13, 2024

Stored XSS in Sentry 10.0.0 through 24.7.0 allows remote authenticated users to execute scripts through malicious external issues. External-issue mapping code interpolates integration-controlled URLs and labels into anchor-tag strings that the Issues page renders as HTML instead of returning structured fields. Exploitation requires a self-hosted instance, an untrusted Integration Platform integration, and a user viewing the affected issue; enforcing CSP blocks script execution.
