HP has identified and remediated multiple externally reported vulnerabilities within HPLIP. The findings affect several software components that could potentially enable remote code execution, privilege escalation, denial of service, information disclosure, or unauthorized file modification under certain conditions.

CVE-2026-906167.4 ALT6.3%
——2In Flatpak before 1.18.1, a malicious sandboxed app can obtain arbitrary read and write access to files on the host, which can be escalated to arbitrary code execution on the host, a different vulnerability than CVE-2026-76925. Flatpak creates a few app data directories (e.g., /var/cache, /var/data, /var/config, and /var/tmp) in every sandbox on every app launch where, in some cases, components of the path are attacker-controlled. Missing symlink protection can redirect the directories. Some of these directories are bind-mounted by Flatpak by passing the path (e.g., /home/user/.var/app/APP_ID/cache/tmp), which contains attacker-controlled directories (tmp) to bwrap --bind SRC DST. bwrap passes the path on to the kernel, which then follows symlinks. A malicious symlink can point to arbitrary locations on the host and it will become mounted inside the sandbox.3dCVE-2026-771595.5 MED5.8%
——2A symlink-following flaw was found in libvirt's qemuTPMEmulatorPrepareHost() function. The function uses a path-based chown() on the swtpm logfile without checking for symbolic links. A local attacker with access to the swtpm account can replace the logfile with a symlink, causing libvirtd (running as root) to transfer ownership of an arbitrary file to the swtpm user.16hCVE-2026-578255.7 MED24.1%
——7In the opam package before 2.5.2 for OCaml, the sandbox protection mechanism can be bypassed because symlinks are mishandled during use of .install files.3dCVE-2026-799395.8 MED2.4%
——1Dell PowerProtect Cyber Recovery, versions Prior to 20.3, contain an UNIX Symbolic Link (Symlink) Following vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Script injection.16dCVE-2026-750386.1 MED2.2%
——1UNIX symbolic link (symlink) following vulnerability in ilya-zlobintsev/LACT allows for local denial-of-service. This issue affects LACT: through 0.10.0.16dCVE-2026-551686.5 MED43.2%
——13Runtipi is a personal homeserver orchestrator. In 4.10.0 and earlier, Runtipi accepts symbolic links from an attacker-controlled backup archive and copies them into live application paths during the backup restore flow. An authenticated attacker can plant user-config/app.env as a symlink to an arbitrary reachable path and then send PUT /api/user-config/demoapp3:_user with attacker-controlled appEnv content. FilesystemService.writeTextFile() follows the planted link, allowing content to be written outside the intended restore and user-config directory boundary with Runtipi process permissions. This issue is fixed in version 4.10.1.23d
