Sep 17, 2026rabbitmq-c is a C-language AMQP client library for RabbitMQ.CVE-2026-44236 · Other software · alanxz · reported by GitHubHigh 7.1
rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized connection.tune.frame_max value during amqp_login(), and rabbitmq-c accepts the value in amqp_login_inner() in librabbitmq/amqp_socket.c. amqp_tune_connection() in librabbitmq/amqp_connection.c uses frame_max to reallocate the outbound buffer without enforcing AMQP_FRAME_MIN_SIZE. Immediate serialization of connection.tune-ok through amqp_frame_to_bytes() writes beyond the undersized heap allocation, causing memory corruption and likely denial of service. An on-path attacker can also trigger the flaw against plaintext AMQP traffic. Code execution is theoretically possible but was not demonstrated. This issue is fixed in version 0.16.0.

Sep 17, 2026rabbitmq-c is a C-language AMQP client library for RabbitMQ.CVE-2026-44235 · Other software · alanxz · reported by GitHubMedium 6.5
rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized HEADER or METHOD frame during client login and cause unsigned size_t underflow in amqp_handle_input() in librabbitmq/amqp_connection.c. The parser subtracts HEADER_SIZE, fixed per-frame fields, and FOOTER_SIZE from state->target_size without first checking the minimum frame length. The wrapped encoded.len value is passed through amqp_decode_properties() to amqp_decode_table_internal(), where it defeats bounds checks and causes an out-of-bounds read and process crash. An on-path attacker can also trigger the issue when AMQP traffic is not protected by TLS with certificate validation. The demonstrated impact is denial of service, with no reliable memory disclosure or code execution shown. This issue is fixed in version 0.16.0.

Jun 16, 2023An issue was discovered in the C AMQP client library (aka rabbitmq-c) through 0.13.0 for RabbitMQ.CVE-2023-35789 · Other software · Rabbitmq-c Project · reported by MITREMedium 5.5
An issue was discovered in the C AMQP client library (aka rabbitmq-c) through 0.13.0 for RabbitMQ. Credentials can only be entered on the command line (e.g., for amqp-publish or amqp-consume) and are thus visible to local attackers by listing a process and its arguments.

Dec 1, 2019An issue was discovered in amqp_handle_input in amqp_connection.c in rabbitmq-c 0.9.0.CVE-2019-18609 · Other software · Rabbitmq-c Project · reported by MITRECritical 9.8
An issue was discovered in amqp_handle_input in amqp_connection.c in rabbitmq-c 0.9.0. There is an integer overflow that leads to heap memory corruption in the handling of CONNECTION_STATE_HEADER. A rogue server could return a malicious frame header that leads to a smaller target_size value than needed. This condition is then carried on to a memcpy function that copies too much data into a heap buffer.

Sep 10, 2018The OpenStack RabbitMQ container image insecurely retrieves the rabbitmq_clusterer component over HTTP during the build stage.CVE-2018-14620 · Other software · Red Hat · reported by Red HatMedium 4.7
The OpenStack RabbitMQ container image insecurely retrieves the rabbitmq_clusterer component over HTTP during the build stage. This could potentially allow an attacker to serve malicious code to the image builder and install in the resultant container image. Version of openstack-rabbitmq-container and openstack-containers as shipped with Red Hat Openstack 12, 13, 14 are believed to be vulnerable.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
