# CVE-2025-2905: WSO2 API Manager XML External Entity (XXE) vulnerability

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.3% , percentile 70: FIRST’s model estimates a 1.3% chance of exploitation activity in the next 30 days, higher than 70% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes org.wso2.am:am-distribution-parent (Maven) < 2.1.0, fixed in 2.1.0 . Check your lockfile, including transitive dependencies.

## What it is

Due to the improper configuration of XML parser, user-supplied XML is parsed without applying sufficient restrictions, enabling XML External Entity (XXE) resolution in multiple WSO2 Products. A successful XXE attack could allow a remote, unauthenticated attacker to: Read sensitive files from the server’s filesystem. Perform denial-of-service (DoS) attacks, which can render the affected service unavailable.
