A flaw was found in bubblewrap. During sandbox setup, creating files or directories under the new root can follow a parent symlink onto the host via /oldroot, writing attacker-chosen paths outside the sandbox as the launching user. This happens before the sandboxed process starts. This issue is GHSA-pxhw-h44j-8pfx. It is fixed in bubblewrap 0.12.0.

The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to open_tree() with AT_SYMLINK_NOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with an fstab-authorized X-mount.subdir entry can attach a host path at the intended mountpoint.

A local vulnerability in the Winlogbeat Windows installer caused runtime files to be placed in a directory writable by unprivileged users. A low-privileged attacker with existing access to the system could pre-position malicious filesystem links, causing a subsequent elevated Winlogbeat operation to write to or delete arbitrary files. Successful exploitation could result in a denial of service.

RubyGems fails to re-validate path containment after filesystem symlink resolution during gem extraction. When a pre-existing symlink inside the destination directory points outside the extraction root, extracted files that appear to be written under the destination directory can instead be written outside of it, breaking the extraction safety boundary. The fix resolves the real path of the parent…

Vulnerabilidad alta en gitoxide anterior a 0.52.1 permite inyección de metadatos de submódulos

gitoxide versiones anteriores a 0.52.1 presenta una vulnerabilidad que permite a atacantes seguir enlaces simbólicos en el archivo .gitmodules del árbol de trabajo, facilitando la inyección de bytes maliciosos en metadatos de submódulos. Un repositorio malicioso puede redirigir la lectura de configuración hacia archivos externos arbitrarios, exponiendo información controlada por el atacante en nombres, rutas y URLs de submódulos. Afecta principalmente a equipos de desarrollo que utilizan gitoxide para control de versiones en México y Latinoamérica.

openssl-encrypt (pip package) before 1.4.9 contains a symlink-following flaw in its verify-usb v2 added-file allowlist scan. The scan enumerated the drive with rglob(), which in CPython does not descend into symlinked directories and treats the symlink as an ordinary directory, while O_NOFOLLOW on the hash side binds only the final path component.

Vulnerabilidad de escalada de privilegios en CodeMeter Runtime (CVE-2026-81572)

La herramienta cmu.exe en CodeMeter Runtime crea archivos temporales predecibles sin validar reparse points de NTFS (junctions y symbolic links), permitiendo que un atacante local redirija operaciones de archivo hacia rutas arbitrarias del sistema. Dado que CodeMeter ejecuta con privilegios de Sistema, esta vulnerabilidad posibilita escalada de privilegios y comprometer servidores, bases de datos y aplicaciones altas en infraestructuras de LATAM que dependan de este software de protección de licencias.

A flaw was found in sos clean, a utility within the sos package. This vulnerability allows a local attacker to perform arbitrary file creation or overwrite. By crafting a malicious tar archive, an attacker can exploit a path traversal issue during tar extraction, where symlink and hardlink targets are not properly validated. This enables the attacker to write files to arbitrary locations on the sy…
