CVE-2026-76977 SAP_SE CVE debrief

Who should care

Defenders responsible for SAP UI5 applications, security teams, and administrators should assess exposure and prioritize verification of framing restrictions bypass. They should also review and update SAP UI5 configurations to prevent unauthorized actions and verify the integrity impact of potential attacks. Additionally, operators and platform administrators should be aware of the potential consequences of this vulnerability and take steps to mitigate its

Why it matters

CVE-2026-76977 allows attackers to bypass framing restrictions in SAP UI5, potentially leading to low integrity impact. Defenders should prioritize verification of exposure and assess potential consequences.

• Defenders should verify exposure of SAP UI5 applications to framing restrictions bypass
• Assess the integrity impact of potential attacks on SAP UI5 applications
• Prioritize review and update of SAP UI5 configurations to prevent unauthorized actions

Technical summary

SAP UI5 does not sufficiently validate the parent frame's origin against the configured allowlist, allowing an unauthenticated attacker to host a malicious page and bypass framing restrictions. This could trick an authenticated victim into performing unintended actions, resulting in a low impact on integrity. Defenders should prioritize verifying exposure of SAP UI5 applications to framing restrictions bypass and assess the integrity impact of potential attacks. The vulnerability affects SAP UI5 applications, and defenders should review and update SAP UI5 configurations to prevent unauthorized actions.

Defensive priority

Defenders should prioritize verifying exposure of SAP UI5 applications to framing restrictions bypass and assess the integrity impact of potential attacks.

Recommended defensive actions

• Verify SAP UI5 applications are configured with proper framing restrictions allowlist
• Assess exposure of SAP UI5 applications to potential framing restrictions bypass
• Review and update SAP UI5 configurations to prevent unauthorized actions
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, but do not specify versions or provide additional information on exploitation or remediation. Defenders should verify exposure of SAP UI5 applications to framing restrictions bypass and assess the integrity impact of potential attacks. The CVE Program and NVD entries offer initial details, but further verification tasks are needed to understand affected scope and potential consequences.
