Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Affected: music-metadata versions below 11.16.0 on npm. The source says the bug exists only on the master branch and is not in the latest npm release (11.14.0) or earlier, and it is fixed in 11.16.0. An attacker who can supply a crafted 48-byte MP4 file to a parse call (for example through an upload) can make the MP4 stsd box parser loop forever, blocking the Node.js event loop with no authentication needed. Upgrade to music-metadata 11.16.0 or later.
