CVE-2026-27904: minimatch ReDoS: nested *() extglobs generate catastrophically backtracking regular expressions

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.52% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: nodejs-docs (AlmaLinux:10) 1:22.22.2-1.el10_1; nodejs (AlmaLinux:8) 1:20.20.2-1.module_el8.10.0+4165+3f200bda, 1:22.22.2-1.module_el8.10.0+4158+e796f37f; nodejs-devel (AlmaLinux:8) 1:20.20.2-1.module_el8.10.0+4165+3f200bda, 1:22.22.2-1.module_el8.10.0+4158+e796f37f.

Low priority for now. Upgrade to nodejs-docs (AlmaLinux:10) 1:22.22.2-1.el10_1; nodejs (AlmaLinux:8) 1:20.20.2-1.module_el8.10.0+4165+3f200bda, 1:22.22.2-1.module_el8.10.0+4158+e796f37f; nodejs-devel (AlmaLinux:8) 1:20.20.2-1.module_el8.10.0+4165+3f200bda, 1:22.22.2-1.module_el8.10.0+4158+e796f37f or later.

Primary sources: NVD · CVE.org · FIRST EPSS

minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Prior to version 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.4, nested `*()` extglobs produce regexps with nested unbounded quantifiers (e.g. `(?:(?:a|b)*)*`), which exhibit catastrophic backtracking in V8. With a 12-byte pattern `*(*(*(a|b)))` and an 18-byte non-matching input, `minimatch()` stalls for over 7 seconds. Adding a single nesting level or a few input characters pushes this to minutes. This is the most severe finding: it is triggered by the default `minimatch()` API with no special options, and the minimum viable pattern is only 12 bytes. The same issue affects `+()` extglobs equally. Versions 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.4 fix the issue.
