Línea de trabajo

Abre Cargo.toml y localiza las entradas de zip en [dependencies] y [build-dependencies]; comprueba los requisitos de versión y la configuración de características existente de ambas. Eleva cada versión mínima a 9.0.5 y, después, inspecciona Cargo.lock. Valida la configuración predeterminada, las configuraciones include-zip y no-unsafe, y el empaquetado de reglas. El trabajo estará terminado cuando ambas declaraciones excluyan las versiones afectadas y esas configuraciones se compilen con una versión de ZIP resuelta segura.

Descripción

Summary

Please raise the minimum zip version to 9.0.5 in both the runtime and build dependency declarations to exclude versions affected by CVE-2026-115905 / GHSA-m665-v7pm-7grj.

Advisory: https://github.com/advisories/GHSA-m665-v7pm-7grj

  • Affected versions: <= 9.0.4
  • First patched version: 9.0.5

Current upstream state

Checked main at commit c6bba2f3a25a2a5f0a861af17f4772c0bef844ee:

  • Cargo.lock already selects zip 9.1.3, outside this advisory's affected range. A lockfile-only update is therefore not needed on current main.
  • Both [dependencies] and [build-dependencies] still declare zip with version = "9.0", which permits affected 9.0.x versions.

Sources:

Why the lockfile alone is not sufficient

Downstream applications consuming MathCAT as a dependency resolve against their own lockfiles; MathCAT's repository lockfile does not force their resolved ZIP version. An existing downstream lockfile can retain an affected version while still satisfying the current "9.0" requirement.

PR #861 upgraded ZIP to address earlier extraction advisories, but its lockfile selected 9.0.4, which is within this advisory's affected range. The newer main lockfile resolves that for current locked builds, while the declared minimum remains permissive.

Suggested change

For both ZIP declarations, raise the requirement to version = "9.0.5" (or a newer compatible minimum), preserving the existing default-features = false and features = ["deflate", "bzip2"] settings.

  • Raise the minimum in both runtime and build dependencies.
  • Keep all resolved ZIP versions outside the advisory's affected range and verify the full dependency graph.
  • Validate default, include-zip, and no-unsafe configurations and rules packaging.
  • Include the tightened requirement in an appropriate crates.io release; already published crate versions cannot be overwritten.

Scope

The advisory concerns parser differences between ZIP local-file and central-directory headers. This report requests dependency hardening against the published advisory; it does not assert a confirmed exploitable RCE path in MathCAT itself.
