CVE-2026-1110 identifies a buffer overflow vulnerability in the rtsp_parse_method function of the cijliu librtsp library, a component used for handling RTSP (Real Time Streaming Protocol) communications. The vulnerability arises from improper handling of input data during the parsing of RTSP methods, which can lead to a buffer overflow condition. This flaw can be triggered by a local attacker with low privileges, as the attack vector is limited to local host access. The buffer overflow could potentially allow an attacker to corrupt memory, leading to arbitrary code execution, denial of service, or information disclosure depending on the exploitation context. The vulnerability has a CVSS 4.8 score, reflecting medium severity, with attack vector local, low complexity, no user interaction, and partial impact on confidentiality, integrity, and availability. Due to the product’s continuous delivery and rolling release model, specific affected versions and patches are not clearly identified, and the vendor has not responded to disclosure attempts. No known exploits have been reported in the wild, but the lack of vendor engagement and patch availability increases risk for users relying on this library in local environments.

The primary impact of CVE-2026-1110 is on systems using the cijliu librtsp library locally, where an attacker with local access could exploit the buffer overflow to execute arbitrary code, crash applications, or leak sensitive information. This could compromise the confidentiality, integrity, and availability of affected systems. Since the attack requires local access and low privileges, remote exploitation is not feasible, limiting the threat scope. However, in environments where multiple users share access or where local access is attainable through other vulnerabilities or misconfigurations, the risk is elevated. The absence of vendor patches and version clarity complicates mitigation efforts, potentially prolonging exposure. Organizations embedding this library in RTSP-related applications or services may face increased risk of local privilege escalation or denial of service, impacting operational stability and security.

Organizations should immediately audit their use of the cijliu librtsp library to identify affected deployments. Since no official patches or version details are available, mitigation should focus on restricting local access to systems running this library, enforcing strict user privilege separation, and monitoring for unusual local activity. Employing application sandboxing or containerization can limit the impact of potential exploitation. Additionally, code review or replacement of the vulnerable rtsp_parse_method function with a safer implementation may be necessary for in-house or open-source users. Network segmentation and limiting access to RTSP services to trusted users can reduce exposure. Continuous monitoring for updates from the vendor or community is critical, and organizations should be prepared to apply patches promptly once available. Finally, integrating host-based intrusion detection systems (HIDS) to detect anomalous memory corruption attempts can provide early warning.
