CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Upgrading the affected component is recommended.

Detailsinfo

A vulnerability, which was classified as problematic, has been found in Apache TomEE. Affected by this issue is an unknown code block of the component Session Bean Passivation. The manipulation with an unknown input leads to a deserialization vulnerability. Using CWE to declare the problem leads to CWE-502. The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. Impacted is confidentiality, integrity, and availability. CVE summarizes:

When a non-default stateful session bean passivation strategy is configured, passivated bean state is written to predictably named files in the shared system temporary directory, reusing files that already exist there, and is deserialized on activation. A local attacker who can write to that directory can read passivated session state or supply data that the server deserializes, potentially leading to code execution as the server process. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

The advisory is available at lists.apache.org. This vulnerability is handled as CVE-2026-111241 since 10/15/2026. The exploitation is known to be easy. Local access is required to approach this attack. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 11/10/2026).

Upgrading to version 10.3.0 or 11.0.0-M2 eliminates this vulnerability.
