{"cve":"CVE-2026-77404","nvd":{"published":"2026-09-16T15:17:47.067","modified":"2026-09-23T18:19:19.803","status":"Awaiting Analysis","description":"RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, URI.String in uri.go concatenates CertFile, KeyFile, CACertFile, and ServerName values directly into an AMQPS query string instead of encoding them as URL query parameters with url.Values. If an application accepts a TLS asset path containing ampersand or equals delimiters and later reparses the serialized URI with ParseURI, the embedded delimiters can create or overwrite connection options, including paths to TLS certificate, key, or CA files. This can corrupt connection configuration or select unintended local cryptographic assets. This issue is fixed in version 1.13.0.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:L","score":8.7},"cvss_v3":null,"cwes":["CWE-116"],"references":["https://github.com/rabbitmq/amqp091-go/commit/743d488e46955fe7ffc55506fe2c401d01216783","https://github.com/rabbitmq/amqp091-go/pull/352","https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0","https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-465g-fh3v-9jw4"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-77404","score":0.00104,"percentile":0.01026,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-465g-fh3v-9jw4","url":"https://osv.dev/vulnerability/GHSA-465g-fh3v-9jw4","summary":"RabbitMQ amqp091-go: Connection Configuration Overwrite via Unsanitized TLS Path Parameter Injection","modified":"2026-10-01T20:56:11.411656712Z","packages":[{"ecosystem":"Go","name":"github.com/rabbitmq/amqp091-go","purl":"pkg:golang/github.com/rabbitmq/amqp091-go","ranges":["<1.13.0"],"fixed":["1.13.0"]}]},{"id":"GO-2026-6493","url":"https://osv.dev/vulnerability/GO-2026-6493","summary":"RabbitMQ amqp091-go: Connection Configuration Overwrite via Unsanitized TLS Path Parameter Injection in github.com/rabbitmq/amqp091-go","modified":"2026-10-01T20:45:11.266820852Z","packages":[{"ecosystem":"Go","name":"github.com/rabbitmq/amqp091-go","purl":"pkg:golang/github.com/rabbitmq/amqp091-go","ranges":["<1.13.0"],"fixed":["1.13.0"]}]}],"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).
