CVE-2026-34480: log4j-core vulnerability flagged in saspy #666

Description

@jkblr

Artifactory/JFrog Xray is flagging saspy (currently latest: 5.107.1) as affected by CVE-2026-34480 due to its bundled org.apache.logging.log4j:log4j-core dependency.

About the CVE

CVE-2026-34480 affects Apache Log4j Core's XmlLayout in versions up to and including 2.25.3. It fails to sanitize characters forbidden by the XML 1.0 specification, which can result in either malformed XML output or exceptions that drop log events entirely — effectively a denial of service for logging operations.

  • Severity: Medium (CVSS 6.9)
  • Fix: Upgrade log4j-core to 2.25.4
  • Published: April 10, 2026
