# CVE-2024-52316: Apache Tomcat - Authentication Bypass

**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 6.2% , percentile 94: FIRST’s model estimates a 6.2% chance of exploitation activity in the next 30 days, higher than 94% of all scored CVEs (elevated). 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.apache.tomcat:tomcat-catalina (Maven) < 9.0.96, fixed in 9.0.96 ; org.apache.tomcat:tomcat-catalina (Maven) >= 10.1.0-M1, < 10.1.30, fixed in 10.1.30 ; org.apache.tomcat:tomcat-catalina (Maven) >= 11.0.0-M1, <= 11.0.0-M26, fixed in 11.0.1 . Check your lockfile, including transitive dependencies.

## What it is

Unchecked Error Condition vulnerability in Apache Tomcat. If Tomcat is configured to use a custom Jakarta Authentication (formerly JASPIC) ServerAuthContext component which may throw an exception during the authentication process without explicitly setting an HTTP status to indicate failure, the authentication may not fail, allowing the user to bypass the authentication process. There are no known Jakarta Authentication components that behave in this way. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M26, from 10.1.0-M1 through 10.1.30, from 9.0.0-M1 through 9.0.95. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other EOL versions may also be affected. Users are recommended to upgrade to version 11.0.0, 10.1.31 or 9.0.96, which fix the issue.

## Affected packages

- Maven `org.apache.tomcat:tomcat-catalina` < 9.0.96 → fixed: 9.0.96
- Maven `org.apache.tomcat:tomcat-catalina` >= 10.1.0-M1, < 10.1.30 → fixed: 10.1.30
- Maven `org.apache.tomcat:tomcat-catalina` >= 11.0.0-M1, <= 11.0.0-M26 → fixed: 11.0.1

## Affected products (CVE record)

- Apache Software Foundation Apache Tomcat: 11.0.0-M1 <= 11.0.0-M26, 10.1.0-M1 <= 10.1.30, 9.0.0-M1 <= 9.0.95, 8.5.0 <= 8.5.100

## Severity

- CISA-ADP CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 6.25% probability of exploitation activity in the next 30 days; percentile 94.
