{"cve":"CVE-2026-77410","nvd":{"published":"2026-09-16T15:17:50.430","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, Channel.recvContent in channel.go preallocates the message body slice with the uint64 ch.header.Size value supplied by an AMQP content header without capping the allocation to the negotiated Connection.Config.FrameSize value. A malicious or compromised broker can send an extreme declared body size and cause the Go runtime to attempt a correspondingly large allocation before body data is received. The allocation can exhaust memory and terminate the client process. This issue is fixed in version 1.13.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","score":8.9},"cvss_v3":null,"cwes":["CWE-789"],"references":["https://github.com/rabbitmq/amqp091-go/commit/91b65fa0096a99a580cf51a31b24028ff1c60382","https://github.com/rabbitmq/amqp091-go/pull/346","https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0","https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-r9c8-gcjp-xfwh"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-77410","score":0.00524,"percentile":0.44444,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-r9c8-gcjp-xfwh","url":"https://osv.dev/vulnerability/GHSA-r9c8-gcjp-xfwh","summary":"RabbitMQ amqp091-go: Resource Exhaustion (OOM) via Unbounded Body Buffer Allocation","modified":"2026-10-01T20:56:22.805183146Z","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-2026-6500","url":"https://osv.dev/vulnerability/GO-2026-6500","summary":"RabbitMQ amqp091-go: Resource Exhaustion (OOM) via Unbounded Body Buffer Allocation in github.com/rabbitmq/amqp091-go","modified":"2026-10-01T20:45:11.275893019Z","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).
