CVE ID :CVE-2026-55160
Published : Sept. 28, 2026, 6:17 p.m. | 55 minutes ago
Description :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.
Severity: 7.6 | HIGH
