CVE-2026-73566

CVE-2026-73566 affects node-tar prior to 7.5.21. The filesFilter in src/list.ts uses a recursive mapHas to walk entry paths upward with path.dirname(), and with tar.t(...) or tar.x(...) and a non-empty member-selection list, a crafted GNU long-path header can reach Parser[CONSUMEHEADER] in src/pa...

commons-configuration: Apache Commons Configuration: Denial of Service via uncontrolled recursion with crafted YAML input

A flaw was found in Apache Commons Configuration. When processing an untrusted configuration file, a remote attacker could provide specially crafted YAML input with cycles. This could lead to an uncontrolled recursion, causing a StackOverflowError and resulting in a Denial of Service DoS for the...
