CVE-2026-25762
Published: 06 February 2026
Summary
CVE-2026-25762 is a high-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in Adonisjs Bodyparser. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 11.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SC-5 (Denial-of-service Protection) and SC-6 (Resource Availability).
Deeper analysis
CVE-2026-25762 is a denial-of-service (DoS) vulnerability in the multipart file handling logic of the @adonisjs/bodyparser package, a component of the AdonisJS TypeScript-first web framework. Affecting versions prior to 10.1.3 and 11.0.0-next.9, the issue arises when the multipart parser accumulates an unbounded amount of data in memory during file type detection on uploads. This leads to excessive memory consumption and potential process termination. The vulnerability is rated 7.5 on the CVSS 3.1 scale (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and maps to CWE-400 (Uncontrolled Resource Consumption) and CWE-770 (Allocation of Resources Without Limits or Throttling).
Remote attackers can exploit this vulnerability without authentication or user interaction by sending specially crafted multipart file upload requests over the network. The low attack complexity allows unauthenticated parties to trigger memory exhaustion, causing the affected AdonisJS application to crash and deny service to legitimate users.
The vulnerability has been addressed in @adonisjs/bodyparser versions 10.1.3 and 11.0.0-next.9, as detailed in the package release notes and the AdonisJS core security advisory (GHSA-xx9g-fh25-4q64). Security practitioners should upgrade to these patched versions to mitigate the issue.
