CVE-2026-71246
Pixelfed - Authenticated SSRF via Remote URL Search
CVSS Score
4.3
EPSS Score
0.0%
EPSS Percentile
0th
Pixelfed's SearchController (behind the auth middleware) accepts a URL via its remote-search parameters and fetches it server-side through ActivityPubFetchService, whose validateUrl only blocks the literal hosts 127.0.0.1, localhost, and ::1 and requires https, without checking the resolved IP against private, internal, or link-local ranges (e.g. 169.254.169.254).
