CVE-2026-11502: A weakness has been identified in JeecgBoot up to 3.9.2. Impacted is the function HttpServletResponse.sendRedirect of the file jeecg-module-system/jeecg-system-biz/src/main/java/org/jeecg/modules/system/controller/ThirdLoginController.java of the component Third-Party Login. This manipulation of the argument state causes open redirect. The attack can be initiated remotely. A high degree of complexity is needed for the attack. The exploitability is considered difficult. The exploit has been made available to the public and could be used for attacks. The project replied: "After evaluation, this vulnerability has low exploitability in real-world scenarios: 1) Exploiting this vulnerability requires attackers to use social engineering techniques to induce victims to actively click on an OAuth login link constructed by the attacker; it cannot be triggered passively. 2) Third-party login (DingTalk/WeChat, etc.) is an optional feature and may not be enabled in most projects."
The exploitability of CVE-2026-11502 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-2026-11502 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.
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-2026-11502, 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-2026-11502, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
