CVE-2026-44881

Summary: Portainer Community Edition before fixes is vulnerable to arbitrary file read via Git-symlink injection when deploying stacks from Git repositories. During Git-backed stack creation/update, go-git v5 may create real OS symlinks for most files (except .gitmodules). The GET /api/stacks/{id...

GHSA-RPGQ-M5FP-32WR Portainer Has an Arbitrary File Read via Git Symlink Injection in Stack Auto-Update

Summary Portainer supports deploying stacks from Git repositories. When a Git-backed stack is created or updated, Portainer clones the repository using go-git v5, which translates Git blob entries with mode 0o120000 symlink into real OS symlinks on the host filesystem via os.Symlink. The only ent...

Path Traversal

@backstage/backend-common is vulnerable to Path Traversal. The vulnerability is due to improper path checks in the resolveSafeChildPath function within paths.ts. Attackers could exploit this weakness to conduct path traversal attacks if they can inject symlink paths...

Path traversal

@backstage/backend-common is a common functionality library for backends for Backstage, an open platform for building developer portals. In @backstage/backend-common prior to versions 0.21.1, 0.20.2, and 0.19.10, paths checks with the resolveSafeChildPath utility were not exhaustive enough, leadi...
