CVE-2026-102554

HIGHCVSS 8.2/10

Last modified

CVE-2026-102554 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. Allocation of resources without limits or throttling (CWE-770) during Java object deserialization in Google Guava versions 4.0 through 33.7.1 allows an attacker to cause a Denial of Service via OutOfMemoryError. When deserializing CompactHashMap, CompactHashSet, or MapMakerInternalMap instances, Guava eagerly allocates an array based on a caller-specified size parameter without throttling, permitting memory exhaustion from crafted serialization streams..
