{"cve":"CVE-2025-65942","nvd":{"published":"2025-11-25T23:15:47.923","modified":"2026-10-19T13:10:00.110","status":"Deferred","description":"VictoriaMetrics is a scalable solution for monitoring and managing time series data. In versions from 1.0.0 to before 1.110.23, from 1.111.0 to before 1.122.8, and from 1.123.0 to before 1.129.1, affected versions are vulnerable to DoS attacks because the snappy decoder ignored VictoriaMetrics request size limits allowing malformed blocks to trigger excessive memory use. This could lead to OOM errors and service instability. The fix enforces block-size checks based on MaxRequest limits. This issue has been patched in versions 1.110.23, 1.122.8, and 1.129.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L","score":2.7},"cwes":["CWE-770"],"references":["https://github.com/VictoriaMetrics/VictoriaMetrics/commit/51b44afd34d2c9a392d4ebedeeb5b4a7f5beca24","https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.110.23","https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.122.8","https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.129.1","https://github.com/VictoriaMetrics/VictoriaMetrics/security/advisories/GHSA-66jq-2c23-2xh5"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:16:02.354564667+00:00"},"epss":{"cve":"CVE-2025-65942","score":0.00366,"percentile":0.30203,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-66jq-2c23-2xh5","url":"https://osv.dev/vulnerability/GHSA-66jq-2c23-2xh5","summary":"VictoriaMetrics' Snappy Decoder DoS Vulnerability is Causing OOM","modified":"2026-09-10T03:50:30.473392190Z","packages":[{"ecosystem":"Go","name":"github.com/VictoriaMetrics/VictoriaMetrics","purl":"pkg:golang/github.com/VictoriaMetrics/VictoriaMetrics","ranges":[">=1.123.0 <1.129.1"],"fixed":["1.129.1"]},{"ecosystem":"Go","name":"github.com/VictoriaMetrics/VictoriaMetrics","purl":"pkg:golang/github.com/VictoriaMetrics/VictoriaMetrics","ranges":[">=1.111.0 <1.122.8"],"fixed":["1.122.8"]},{"ecosystem":"Go","name":"github.com/VictoriaMetrics/VictoriaMetrics","purl":"pkg:golang/github.com/VictoriaMetrics/VictoriaMetrics","ranges":[">=1.0.0 <1.110.23"],"fixed":["1.110.23"]}]},{"id":"GO-2025-4161","url":"https://osv.dev/vulnerability/GO-2025-4161","summary":"VictoriaMetrics' Snappy Decoder DoS Vulnerability is Causing OOM in github.com/VictoriaMetrics/VictoriaMetrics","modified":"2026-02-04T03:01:32.282457Z","packages":[{"ecosystem":"Go","name":"github.com/VictoriaMetrics/VictoriaMetrics","purl":"pkg:golang/github.com/VictoriaMetrics/VictoriaMetrics","ranges":["<1.110.23",">=1.111.0 <1.122.8",">=1.123.0 <1.129.1"],"fixed":["1.110.23","1.122.8","1.129.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
