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:
