    CVE-2026-55160 (GCVE-0-2026-55160)

    Vulnerability from nvd – Published: 2026-09-28 17:52 – Updated: 2026-09-28 18:35
    VLAI
    Title
    Authenticated Server-Side Request Forgery (SSRF) via feed URL in Stringer
    Summary
    Stringer is a self-hosted, anti-social RSS reader. Prior to commit 75cb095, an unrestricted Server-Side Request Forgery (SSRF) vulnerability allows any authenticated user to force the Stringer server to send arbitrary HTTP/HTTPS requests to internal networks, localhost services, and cloud metadata endpoints (e.g. AWS IMDS 169.254.169.254). When self-service signup is enabled (Setting::UserSignup), even a low-privileged registered user can exploit this to scan internal services or steal cloud IAM credentials. This issue has been patched via commit 75cb095.
