Collected exploitation and prediction evidence

Risk source coverage

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

OW2 ASM 3.0 before 9.11 Exponential Memory Allocation in JSRInlinerAdapter

OW2 ASM 3.0 before 9.11 contains an uncontrolled memory allocation vulnerability in the asm-commons JSRInlinerAdapter that inlines JSR/RET subroutines without memory or work limits. Attackers can supply a crafted class file with nested subroutines to force O(2^n) memory allocation, causing an OutOfMemoryError that crashes the JVM.
