CVE-2026-114457

Full vulnerability record from the local CVENow database.

Description

A flaw was found in mod_qos. An unauthenticated remote attacker could cause a Denial of Service (DoS) by sending a specially crafted JSON request when JSON body filtering is enabled. Due to improper string termination during the processing of percent-encoded input, the module reads past allocated memory boundaries, which can cause an Apache worker process to crash.
