CVE-2026-76977: CWE-1289: Improper Validation of Unsafe Equivalence in Input in SAP_SE SAPUI5(Frame Options Allowlist)
CVE-2026-76977 is a medium severity vulnerability in SAPUI5's Frame Options Allowlist where the parent frame's origin is not properly validated. This allows an unauthenticated attacker to host a malicious page that can bypass framing restrictions. If an authenticated user visits the malicious page and interacts with it, the attacker could trick the user into performing unintended actions, impacting integrity but not confidentiality or availability.
AI Analysis
Technical Summary
SAPUI5 does not sufficiently validate the origin of the parent frame against the configured allowlist, enabling an attacker to bypass framing restrictions by hosting a malicious page. This improper validation of unsafe equivalence (CWE-1289) can lead to an attacker tricking an authenticated victim into unintended actions, resulting in a low integrity impact. There is no confidentiality or availability impact. The vulnerability affects specific SAPUI5 versions (=754, =755, =756, =757, =758, =816). No official remediation or patch is currently documented.
Potential Impact
The vulnerability allows an unauthenticated attacker to bypass frame restrictions and potentially trick authenticated users into unintended actions, causing a low impact on data integrity. There is no impact on confidentiality or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or remediation level has been published by SAP as of now. Users should monitor SAP advisories for updates and consider restricting frame embedding or applying custom frame validation as a temporary measure.
