CVE-2026-7135: A security flaw has been discovered in GPAC up to 26.03-DEV-rev105-g8f39a1eb3-master. Affected by this vulnerability is the function elng_box_read of the file src/isomedia/box_code_base.c of the component MP4Box. Performing a manipulation of the argument elng results in out-of-bounds read. The attack needs to be approached locally. The exploit has been released to the public and may be used for attacks. The patch is named cf6ac48c972eaaee2af270adc3f36615325deb3e. The affected component should be upgraded.
The exploitability of CVE-2026-7135 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2026-7135 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-7135, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-7135, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
