CVE-2026-59879 Immutable.js `List` 32-bit trie overflow → unrecoverable DoS

Immutable.js provides many Persistent Immutable data structures. Prior to 4.3.9 and 5.1.8, Listset, ListsetSize, ListsetIn, ListupdateIn, and the functional set, setIn, and updateIn mishandle an index or size in the range 2 30 to 2 31 in setListBounds in src/List.js, causing an empty List to ente...

CVE-2026-59880

Immutable.js contains a HashCollision vulnerability in Map/Set keys prior to version 4.3.9 and 5.1.8: an adversary who controls inserted keys can craft many hash collisions in a HashCollisionNode, causing linear scans and CPU exhaustion during insertion and lookup. The issue is fixed in 4.3.9 and...

Git Hash Chain Malleability

This whitepaper demonstrates that signed Git commits are not uniquely bound to their commit hashes, even when they display a valid "Verified" badge on GitHub. The authors show that attackers can transform the signature encoding of an existing signed commit—without possessing the private signing...

CVE-2026-13201

A flaw was found in KubeVirt's safepath package used by virt-handler. The OpenAtNoFollow function uses OPATH|ONOFOLLOW to obtain a file descriptor to a path leaf, but downstream operations resolve the path via /proc/self/fd/N using link-following syscalls. When the leaf is a symlink, the kernel...

Overview Affected versions of this package are vulnerable to UNIX Symbolic Link Symlink Following in the OpenAtNoFollow process. An attacker can cause unintended file ownership or permission changes on host files by placing a symlink in the virt-launcher filesystem, which is then followed via...
