High [CVE-2026-73646] Information disclosure via path traversal in source map auto-loading
PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules into an Abstract Syntax Tree. Prior to 8.5.18, lib/previous-map.js loadMap() passes attacker-controlled sourceMappingURL values to join(dirname(opts.from), annotation), and loadFile() permits traversed or absolute.map paths, allowing untrusted CSS processed without map: false to disclose sourcesContent from arbitrary reachable.map files through result.map. This issue is fixed in version 8.5.18. A flaw was found in PostCSS. An attacker can exploit a path traversal vulnerability by providing specially crafted `sourceMappingURL` values in untrusted CSS files. This allows the attacker to disclose sensitive `sourcesContent` from arbitrary `.map` files accessible on the system, leading to information disclosure. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-22.

High [CVE-2026-19693] Arbitrary file write via symlink in archive
extract-zip through 2.0.1 containment-checks only the parent directory of each archive entry and never the entry's own final path component, so an archive containing two entries with identical names - a symlink whose target is outside the destination, followed by a regular file - writes through the planted symlink and yields an arbitrary file write outside the destination directory. By crafting a malicious zip archive containing a symbolic link (symlink) and a regular file with the same name, the attacker can bypass security checks. The extract-zip utility incorrectly validates only the parent directory, enabling the attacker to write files to arbitrary locations on the system. The flaw arises from insufficient validation of archive entries, allowing a remote attacker to write files to arbitrary locations on the system by providing a specially crafted zip archive. This requires user interaction to extract the malicious archive, but successful exploitation could lead to significant system integrity and availability compromise. Red Hat severity: Important — CVSS 8.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H). Weakness: CWE-59. Affected products named by the advisory: Node HealthCheck Operator; OpenShift Pipelines; Red Hat Build of Podman Desktop; Red Hat Ceph Storage 4; and 6 more.
