0 CVE-2026-68494 is a high-severity vulnerability in FasterXML jackson-core affecting versions from 2.15.0 through 2.18.7, 2.19.0 through 2.21.3, and 3.0.0 through 3.1.3. It involves improper resource allocation without limits in the non-blocking JSON parser, allowing an attacker to cause excessive memory consumption by streaming JSON numbers in many small chunks without terminators. This can lead to JVM heap exhaustion in reactive frameworks using the async parser. The issue does not affect synchronous parsers or async parsers operating on complete input. Exploitation requires only the ability to stream data to a parsing endpoint and no privileges. Join the discussion | CVE Database V5 | 08/04/2026, 14:39:14 UTC Added: 08/04/2026, 14:56:55 UTC |
