Summary IBM Watson Discovery for IBM Cloud Pak for Data affected by vulnerability in log4j-core-2.25.2.jar Vulnerability Details CVEID:CVE-2026-34479 DESCRIPTION: The Log4j1XmlLayout from the Apache Log4j 1-to-Log4j 2 bridge fails to escape characters forbidden by the XML 1.0 standard, producing...

Astra Linux – Vulnerability in Apache Log4j2

The Log4j1XmlLayout from the Apache Log4j 1-to-Log4j 2 bridge fails to escape characters prohibited by the XML 1.0 standard, resulting in malformed XML output. Compatible XML parsers are required to reject documents containing such characters with a fatal error, which may cause downstream log...

Astra Linux – Vulnerability in PHP 7.3

In PHP versions 7.3.x below 7.3.27, 7.4.x below 7.4.15, and 8.0.x below 8.0.2, when using the SOAP extension to connect to a SOAP server, a malicious SOAP server may return malformed XML data as a response. This could cause PHP to access a null pointer, resulting in a crash...

Summary IBM webMethods BPM is dependant on log4j-core which is affected by known vulnerability - CVE-2026-34479 Vulnerability Details CVEID:CVE-2026-34479 DESCRIPTION: The Log4j1XmlLayout from the Apache Log4j 1-to-Log4j 2 bridge fails to escape characters forbidden by the XML 1.0 standard,...

SUSE CVE-2026-81723

NLTK versions before 3.10.3 contain a quadratic CPU exhaustion vulnerability in XMLCorpusView.readxmlfragment that rescans accumulated XML fragments on every 1 KiB block read. Attackers can provide malformed XML corpus files to cause severe CPU consumption and denial of service through affected...

GHSA-VP2X-QP44-57V7 NLTK: Quadratic CPU Exhaustion in `XMLCorpusView._read_xml_fragment()`

Summary XMLCorpusView.readxmlfragment reads a corpus file in 1 KiB blocks, appending each block to a growing fragment string, then calls VALIDXMLRE.matchfragment on the full accumulated buffer every iteration. Because each iteration rescans the entire accumulated fragment, the total amount of wor...

CVE-2026-83614

A flaw was found in xmldom. Two independent quadratic paths in the XML DOM Document Object Model parser can lead to a denial of service DoS. A remote attacker could exploit this by providing specially crafted XML input, causing the parser to repeatedly rescan malformed tag names or reindex and...
