CVE-2026-13401
Description
A flaw was found in perl-XML-Bare. A remote attacker can exploit this vulnerability by providing specially crafted XML input with malformed attributes. This can cause the parserc_parse function to enter an infinite loop, leading to a Denial of Service (DoS) condition where the application becomes unresponsive.
Statement
Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references.
Mitigation
The vulnerability occurs when `perl-XML-Bare` processes malformed XML. To mitigate this issue, applications should avoid parsing XML from untrusted sources using `perl-XML-Bare`. If processing untrusted XML is unavoidable, implement input validation and sanitization before passing data to the `perl-XML-Bare` parser.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Amplification
An infinite loop will cause unexpected consumption of resources, such as CPU cycles or memory. The software's operation may slow down, or cause a long time to respond.
