CVE-2026-118042
Published:November 07, 2026
Updated:November 10, 2026
Google Guava from 13.0 through 33.7.2 is vulnerable to hash flooding in HashBiMap and in the per-key value sets of LinkedHashMultimap. These collections use chained hash tables with no fallback when a bucket grows long, so inserting keys or values that share a hashCode() makes construction quadratic. An application that fills these collections from untrusted input (for example header names, form fields or JSON keys) can be slowed down significantly by a small crafted request, causing denial of service. Fixed in 33.8.0.
