## What is CVE-2026-15379?

CVE-2026-15379 is a medium-severity vulnerability in Broadcom Symantec IT Management Suite, published on 17 Jul 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

The Altiris WMI provider exposes a class (AltirisAgent_Stream) that allows any local standard user to read the contents of any file accessible to the SYSTEM account, bypassing filesystem ACLs. No admin privileges required. The provider reverts to the LocalSystem context when servicing WMI queries without re-impersonating the caller. Any local standard user can therefore read SYSTEM-readable files — including configuration files, service logs, and secrets stored with SYSTEM/Administrator-only ACLs — by querying the provider directly.

Weakness: CWE-269 (Improper Privilege Management)

Exploitation: There is no known exploitation of CVE-2026-15379 in the wild and no public exploit code.

Affected product: Broadcom Symantec IT Management Suite. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
