      HIGHCVE-2026-61814

      AsyncParser can be forced to perform O(n^2) work on the length of the input. When a single JSON token arrives across many small chunks, each absorb call rescans the incomplete token from the start.

      // impact

      Denial of service via CPU exhaustion when parsing untrusted JSON.

      Preconditions:

      • Application uses AsyncParser
      • Attacker can send large tokens with control over chunk sizes.
      // patches

      Fixed in jawn-parser-1.7.0.

      // workarounds

      If you can't upgrade immediately:

      • Use the synchronous Parser.
      • Buffer incoming bytes into larger chunks before calling absorb
