CVE-2026-1464 identifies an integer overflow or wraparound vulnerability (CWE-190) in the MuntashirAkon AppManager application, specifically within the TarUtils.java file of the Apache Commons Compress library's tar modules. This vulnerability arises when the application processes tar archive files and fails to properly handle integer values, leading to overflow or wraparound conditions. Such flaws can cause incorrect calculations of buffer sizes or memory allocations, potentially resulting in buffer overflows, memory corruption, or application crashes. The vulnerability affects all versions of AppManager prior to 4.0.4. The CVSS 4.0 vector indicates the attack vector is local (AV:L), with low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:A). The vulnerability impacts confidentiality, integrity, and availability to a limited extent (VC:L, VI:L, VA:L), with a scope limited to the vulnerable component (S:N). The vulnerability is rated medium severity with a CVSS score of 4.6. There are no known exploits in the wild, and no patches are linked yet, but upgrading to version 4.0.4 or later is recommended once available. The flaw could be exploited by convincing a user to open a crafted tar archive, leading to potential memory corruption and subsequent security issues such as denial of service or limited code execution.

For European organizations, the impact of CVE-2026-1464 depends on the extent to which MuntashirAkon AppManager is used, particularly in environments processing tar archives. Exploitation could lead to partial compromise of confidentiality, integrity, and availability of systems running the vulnerable software. This might manifest as application crashes, denial of service, or limited unauthorized code execution, potentially disrupting business operations or exposing sensitive data. Sectors relying on automated archive processing, such as software development, IT management, or digital forensics, could be more affected. Given the local attack vector and requirement for user interaction, the risk is mitigated somewhat by operational controls but remains significant where users handle untrusted archives. The absence of known exploits reduces immediate threat but does not eliminate future risk. European organizations with stringent compliance requirements should prioritize remediation to avoid regulatory penalties and reputational damage.

1. Upgrade MuntashirAkon AppManager to version 4.0.4 or later as soon as the patch becomes available to address the integer overflow vulnerability. 2. Implement strict input validation and sanitization for all tar archive files processed by the application, ensuring size fields and metadata are within expected bounds. 3. Restrict processing of tar archives from untrusted or unauthenticated sources to minimize exposure to crafted malicious files. 4. Employ application whitelisting and sandboxing techniques to limit the impact of potential exploitation. 5. Monitor application logs for abnormal crashes or errors related to archive processing that could indicate exploitation attempts. 6. Conduct user awareness training to reduce the risk of users opening suspicious or unsolicited archive files. 7. Where possible, isolate systems running AppManager from critical infrastructure to contain potential impacts. 8. Coordinate with vendors and security teams to track patch releases and threat intelligence updates related to this vulnerability.
