Denial Of Service (DoS)

Micronaut Framework is vulnerable to Denial of Service DoS. The vulnerability is due to improper handling of descending array index order in JsonBeanPropertyBinder::expandArrayToThreshold, where crafted form-urlencoded parameters can trigger a non-terminating loop, leading to CPU exhaustion and...

CVE-2026-33012

A flaw was found in Micronaut Framework. Remote attackers can exploit an unbounded cache in the DefaultHtmlErrorResponseBodyProvider component by influencing exception messages, such as through request query parameters. This can lead to uncontrolled memory growth and an OutOfMemoryError, resultin...

CVE-2026-33013

A flaw was found in Micronaut Framework, specifically within the micronaut-core component. This vulnerability allows a remote attacker to cause a Denial of Service DoS by sending crafted indexed form parameters. The flaw occurs because the framework does not correctly handle descending array inde...
