Package : opam CVE ID : CVE-2026-57825

Kate Deplaix reported that .install file directives were insufficiently restricted in OPAM, a package manager for OCaml. Installing files through .install files did not check symlinks resolution on the target path, which could result in directory traversal out of the package area.

For the stable distribution (trixie), this problem has been fixed in version 2.3.0-1+deb13u2.

We recommend that you upgrade your opam packages.

For the detailed security status of opam please refer to its security tracker page at:
