Security readout for executives and security teams
Plain-English summary
CVE-2026-1129 is a SQL injection issue in Yonyou KSOA 9.0. A remote attacker can manipulate an HTTP GET parameter in worksadd.jsp to affect the backend database. Public exploit information reportedly exists. There is no source-confirmed active exploitation and no vendor fix is identified in the provided sources.
Executive priority
Prioritize this for rapid assessment if Yonyou KSOA is used. Public exploit availability and unauthenticated network reachability make exposed KSOA 9.0 instances a meaningful business risk. If not internet-facing, reduce exposure and monitor while awaiting vendor guidance.
Technical view
The flaw affects /worksheet/worksadd.jsp in Yonyou KSOA 9.0, specifically the HTTP GET parameter ID. The CVSS v2 vector is AV:N/AC:L/Au:N with partial confidentiality, integrity, and availability impact. VulDB maps it to CWE-89 and CWE-74. Vendor contact reportedly received no response.
Likely exposure
Organizations running Yonyou KSOA 9.0 are the known affected population. Internet-exposed KSOA portals are higher risk because the CVSS vector indicates network access and no authentication requirement. Exposure for other KSOA versions is not established by the provided sources.
Exploitation context
The source bundle states that exploit information is public and may be used. CISA KEV status is false, and the provided sources do not confirm active exploitation in the wild. Treat the issue as urgent where KSOA 9.0 is reachable from untrusted networks.
Researcher notes
Evidence is centered on VulDB and a public GitHub issue. The affected code path is identified, but vendor confirmation and remediation details are absent. Do not assume other versions are affected. Active exploitation is not established by KEV or the provided sources.
Mitigation direction
- Check Yonyou support channels for an official advisory or fixed version.
- Restrict external access to KSOA, especially /worksheet/worksadd.jsp.
- Require VPN or trusted network access for KSOA administration and workflows.
- Use WAF or gateway filtering for suspicious requests to the affected endpoint.
- Increase monitoring of KSOA web and database activity.
- Back up related databases and verify restoration procedures.
Validation and detection
- Inventory systems running Yonyou KSOA and confirm version 9.0 presence.
- Determine whether KSOA is reachable from the internet or untrusted networks.
- Review access logs for unusual requests to /worksheet/worksadd.jsp using the ID parameter.
- Check vulnerability management tools for coverage referencing CVE-2026-1129 or VDB-341719.
- Confirm whether any vendor-provided update or workaround has become available.
