yopass is a service for securely sharing secrets, passwords, and files. Prior to version 14.7.0, the Prometheus metrics middleware in pkg/server/server.go uses the attacker-controlled r.Method value directly as the method label for yopass_http_requests_total and yopass_http_request_duration_seconds. Because the catch-all route accepts arbitrary HTTP method tokens, an unauthenticated remote attacker can submit many unique methods and create metric series that the Prometheus registry never evicts. The resulting monotonic memory growth can OOM-kill the process, while the expanding registry also degrades /metrics scrape latency and can blind monitoring. This issue is fixed in version 14.7.0.

EchelonGraph scoreLOW confidence
This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
