Privilege escalation via feed-scraping SSRF
Published Jun 4, 2025 · Updated Jun 4, 2025
SSRF in FreshRSS before 1.26.2 allows remote authenticated users to impersonate users and access internal services through feed creation. The add-feed scraper accepts attacker-controlled cURL headers and an internal URL, then XPath extraction returns a target user's CSRF token. Exploitation requires an account, knowledge of the instance IP and an administrator username, and reverse-proxy HTTP authentication that trusts the instance IP; OIDC deployments are not exposed to the demonstrated privilege escalation.
