MEDIUMCVSS 5.5/10

Last modified

CVE-2026-110261 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. OW2 ASM 3.0 before 9.11 contains a denial of service vulnerability that allows attackers to exhaust CPU by supplying crafted class files processed with ClassWriter.COMPUTE_FRAMES. Attackers can craft methods that make the unbounded MethodWriter.computeAllFrames() fix point algorithm converge slowly, tying up transforming threads for unbounded time..
