body-parser is vulnerable to denial of service when url encoding is used

CVE-2025-13466 / GHSA-wqch-xfxh-vrr4

More information

Details

Impact

body-parser 2.2.0 is vulnerable to denial of service due to inefficient handling of URL-encoded bodies with very large numbers of parameters. An attacker can send payloads containing thousands of parameters within the default 100KB request size limit, causing elevated CPU and memory usage. This can lead to service slowdown or partial outages under sustained malicious traffic.

Patches

This issue is addressed in version 2.2.1.

What's Changed

The reason for this release is a fix to the extended urlencoded parser returning objects instead of arrays for large array inputs (> 100) on qs@​6.14.2+. (#​716)

• refactor(json): simplify strict mode error string construction by @​jonchurch in #​692
• fix: correct off-by-one error in parameterCount by @​abhu85 in #​716
• deps(qs): bump qs to 6.15.1 by @​jonchurch in #​722
• Release: 1.20.5 by @​jonchurch in #​721

New Contributors

• @​abhu85 made their first contribution in #​716
