Security readout for executives and security teams
Plain-English summary
CVE-2026-0587 is a cross-site scripting issue in Xinhu Rainrock RockOA’s cover image handling. A logged-in attacker can manipulate the fengmian input so script may run in another user’s browser. This is not a server takeover finding, but it can support session abuse, content tampering, or phishing inside the OA system.
Executive priority
Treat as a near-term application security fix, not an emergency infrastructure incident. Prioritize if RockOA is internet-facing, broadly used internally, or handles sensitive workflow data. Absence of a vendor fix increases the need for exposure reduction and monitoring.
Technical view
VulDB describes XSS in rock_page_gong.php, component Cover Image Handler, via the fengmian argument. CVSS 4.0 is 5.1: network reachable, low complexity, low privileges required, and user interaction required. Sources list RockOA 2.7.0 and 2.7.1, with one submission noting earlier versions may also be affected.
Likely exposure
Organizations running Xinhu Rainrock RockOA 2.7.0 or 2.7.1 are in scope. Earlier versions may be affected, but the public evidence is not definitive. Exposure is higher where authenticated users can reach the Cover Image Handler remotely.
Exploitation context
The source bundle says a public exploit has been released. It is not listed in CISA KEV, and the provided sources do not confirm active exploitation. The CVSS vector indicates an attacker needs low privileges and a victim interaction path.
Researcher notes
Evidence is mainly from CVE/VulDB records. Vendor reportedly did not respond, and no official patch is named in the provided sources. CWE-79 fits the described issue; CWE-94 is also listed but not explained by the available detail.
Mitigation direction
- Check Xinhu or RockOA channels for updated vendor guidance or patches.
- Restrict RockOA access to trusted users and networks where operationally possible.
- Review application-side input validation and output encoding around cover image fields.
- Use web filtering or WAF controls to reduce script injection attempts.
- Monitor VulDB and CVE records for vendor response or revised affected versions.
Validation and detection
- Inventory RockOA deployments and record exact versions.
- Confirm whether rock_page_gong.php and Cover Image Handler are reachable.
- Review access logs for unusual fengmian parameter activity.
- Perform authorized, non-destructive XSS validation in a test environment.
- Check whether any compensating controls block stored script rendering.

CWE-79: User-session and phishing behavior lookup
Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupCWE-94: Code execution behavior lookup
Code execution and unsafe deserialization weaknesses often justify reviewing execution behavior and process telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
