  • CVSS score 9.8 (7.0 or more) and EPSS 0.81 (0.1 or more): a high score and a real chance of exploitation in the next 30 days.

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Struts (org.apache.struts:struts2-core) versions from 2.0.0 before 2.5.33 and from 6.0.0 before 6.3.0.2 are vulnerable to path traversal. An attacker can manipulate file upload parameters to traverse paths, and under some circumstances this can lead to uploading a malicious file that enables remote code execution. Upgrade to Struts 2.5.33 or 6.3.0.2 or later.

Written 7 Nov 2026.
