The remote Debian 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5749 advisory.
- ------------------------------------------------------------------------- Debian Security Advisory DSA-5749-1 [email protected] https://www.debian.org/security/ Salvatore Bonaccorso August 14, 2024 https://www.debian.org/security/faq

Package : flatpak CVE ID : CVE-2024-42472
Chris Williams discovered a flaw in the handling of mounts for persistent directories in Flatpak, an application deployment framework for desktop apps. A malicious or compromised Flatpak app using persistent directories could take advantage of this flaw to access files outside of the sandbox.
Details can be found in the upstream advisory at https://github.com/flatpak/flatpak/security/advisories/GHSA-7hgv-f2j8-xw87
For the stable distribution (bookworm), this problem has been fixed in version 1.14.10-1~deb12u1. To address the vulnerability, flatpak uses a new feature provided in bubblewrap and provided in version 0.8.0-2+deb12u1 along with this update.
We recommend that you upgrade your flatpak packages.
For the detailed security status of flatpak please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/flatpak

Tenable has extracted the preceding description block directly from the Debian security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
