Hi,

The following vulnerability was published for guava-libraries.

CVE-2026-102554[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
