File disclosure and resource exhaustion via XML entities
Published Aug 22, 2023 · Updated Oct 3, 2024
XXE in Python plistlib through 3.9.1 allows attackers to read local files or exhaust resources via a crafted XML plist. The XML plist parser passes entity declarations to Expat without rejecting them, allowing declared entities to be expanded during parsing. Exploitation requires an application to parse attacker-controlled XML plist data; the bounded consequences are file disclosure and resource exhaustion.
