Regular Expression Denial of Service (ReDoS)

Overview Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS through the doSearchString text search routine in the org.jline.builtins.Nano editor. An attacker can hang the editor session and drive CPU usage high by entering a crafted regex search pattern...

CVE-2026-66074

A flaw was found in RabbitMQ. A remote attacker with management privileges could exploit a regular expression regex filter in the management API by providing a specially crafted regex to the ?name= filter. This vulnerability, known as Regular Expression Denial of Service ReDoS, causes excessive C...

CVE-2026-66074 RabbitMQ: ReDoS via management API ?name= filter

RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0, matchvalue/3 passes the user-supplied ?name= regular expression to re:run with no matchlimit option, and executes it once per resource in the result set. OTP's default 10M matchlimit caps ea...
