## What is CVE-2026-11502?

CVE-2026-11502 is a low-severity vulnerability in JeecgBoot, published on 8 Jun 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

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."

Weakness: CWE-601 (URL Redirection to Untrusted Site)

Check this codebase for CVE-2026-11502 and fix it if it is affected.

What it is: CVE-2026-11502 is a low-severity vulnerability in JeecgBoot, published on 8 Jun 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-11502 exists.

Affected product: JeecgBoot. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
