Machine-written summary

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

TwelveMonkeys ImageIO's imageio-metadata package, Maven com.twelvemonkeys.imageio:imageio-metadata, is vulnerable to XML External Entity injection in versions before 3.7.1 because its XML parser for XMP metadata is insecurely initialized. An attacker who can supply an image with a malicious XMP segment, such as through an uploaded profile picture, can trigger the flaw when that metadata is parsed. Upgrade to version 3.7.1 or later.
