0 CVE-2026-91776 is a high-severity vulnerability in FasterXML jackson-databind affecting versions from 2.0.0 through 3.2.2 in various ranges. It involves uncontrolled resource consumption due to caching of attacker-supplied unknown type IDs in the deserializer cache when name-based polymorphism with a fallback is enabled. This can lead to monotonic memory retention and potential denial of service. The vulnerability requires specific application configurations and long-lived ObjectMapper instances. A fix is available that stops caching fallback resolutions for unrecognized IDs and bounds the cache size.
