Title

RabbitMQ amqp091-go: Connection Configuration Overwrite via Unsanitized TLS Path Parameter Injection

Summary

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.

Summary

Red Hat Security Advisory: Red Hat Quay 3.9.27

Severity

Important

Scope

15 vulnerabilities in this advisory, including CVE-2026-77404.

CVE-2026-77404

A flaw was found in RabbitMQ amqp091-go. The URI.String function in uri.go concatenates TLS asset path values directly into an AMQPS query string without proper encoding. If an application processes a TLS asset path containing special characters like ampersand or equals delimiters, these can be misinterpreted during URI re-parsing. This vulnerability could allow an attacker to overwrite connection options, potentially corrupting the connection configuration or selecting unintended local cryptographic assets, leading to a compromise of the TLS connection.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
