EUVD-2026-68102

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 writt...

CVE-2026-82455

RubyGems versions before 4.0.13 are vulnerable to a path traversal issue during gem extraction. The root cause is a failure to re-validate path containment after filesystem symlink resolution : if a pre-existing symlink inside the destination directory points outside the extraction root, extracte...

CVE-2026-65647

CVE-2026-65647 is an improper symlink resolution vulnerability in the Plesk Site Import and Migrator extensions. A remote authenticated (low-privilege) user can leverage this flaw to execute arbitrary code as root , resulting in full compromise of the vulnerable system. The CVSS 4.0 score is 8.7 ...

Astra Linux – Vulnerability in Firefox and Thunderbird

When resolving a symbolic link such as file:///proc/self/fd/1, an error message may be generated if the symbolic link resolves to a string containing uninitialized memory in the buffer. This bug only affects Thunderbird on Unix-based operating systems Android, Linux, MacOS. Windows is unaffected...

CVE-2026-16989

CVE-2026-16989 affects IBM AIX 7.2, 7.3 and IBM PowerVM VIOS 4.1 , where improper resolution of symbolic links allows a local attacker with low privileges to gain elevated privileges (high impact on confidentiality and integrity, no availability impact). The CVSS 3.1 score is 7.1 (HIGH) with a lo...

AZL-95852 CVE-2026-53784 affecting package rsync for versions less than 3.5.0-1

rsync before 3.5.0 contains a path traversal vulnerability that allows remote clients to access files outside the intended module root when use chroot is disabled and the module root path or a component of it is a symlink. The daemon calls chdir to the module root at session initialization withou...

PYSEC-2026-2556 LangChain: Path traversal and sandbox escape in LangChain file-search middleware and loaders

Summary Several LangChain components that resolve filesystem paths or expand search patterns do not consistently confine the resolved path to the intended root directory. Affected behaviors include: a file-search agent middleware that validates a starting directory but not the search pattern or t...

ocaml-opam -- opam install sandbox escape using symlinks

The OCaml Team reports: Installing files through .install files do not check symlinks resolution of the target path, and so can bypass sandboxing. Credits: Reporter: "Kate Deplaix" Remediation Developer: "Nathan Rebours" Remediation Reviewer: "Raja Boujbel" Coordinator: "Hannes Mehnert"...

PT-2026-56690

Name of the Vulnerable Software and Affected Versions opam versions prior to 2.5.2 Description Installing files via .install files does not verify symlink resolution of the target path, which allows for the bypass of sandboxing. An attacker can use a malicious .install file in combination with a...

CVE-2026-44740 go-billy: Lack of depth and cycle detection in symlink resolution may lead to infinite loops and resource exhaustion

Billy is an interface filesystem abstraction for Go. Prior to versions 5.9.0 and 6.0.0-alpha.1, multiple components may improperly handle crafted or malformed input, resulting in panics, infinite loops, uncontrolled recursion, or excessive resource consumption. These issues arise from insufficien...
