CVE-2024-23737Network attack vector

Encryption-key manipulation via forged upload requests

Published Jul 1, 2024 · Updated Mar 18, 2025

CSRF in S/Notify for Jira before 4.0.2 allows remote attackers to replace or remove a user's S/MIME certificate or PGP key. The user-profile upload functionality accepts a forged state-changing request under the logged-in user's session, adding, replacing, or deleting key material. Exploitation requires the upload option to be enabled and a logged-in user to follow a malicious link or visit a malicious site; replacement material must match the user's email address, and successful tampering prevents that user from decrypting notifications.
