CVE-2026-32256 Details
Description
music-metadata is a metadata parser for audio and video media files. Prior to version 11.12.3, music-metadata's ASF parser (`parseExtensionObject()` in `lib/asf/AsfParser.ts:112-158`) enters an infinite loop when a sub-object inside the ASF Header Extension Object has `objectSize = 0`. Version 11.12.3 fixes the issue.
A denial-of-service vulnerability has been identified in the music-metadata library, specifically in versions prior to 11.12.3. The issue arises in the ASF parser's 'parseExtensionObject()' method, where the parser can enter an infinite loop. This occurs when a sub-object within the ASF Header Extension Object has an 'objectSize' of 0. The loop is created because the parser's logic mistakenly allows the read position to move backward, causing the same header to be processed repeatedly without ever exiting the loop.
