AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N
AC:H reflects the mandatory renderer-compromise precondition; UI:R retained for social engineering; C:L only as origin policy bypass yields limited cross-origin read.

Incorrect authorization in Core in Google Chrome prior to 152.0.7977.65 allowed a remote attacker who had compromised the renderer process and leveraged social engineering to bypass web origin policy via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Incorrect authorization in Google Chrome Core prior to 152.0.7977.65 enables a remote attacker who has already compromised the renderer process to bypass the web origin policy by combining that foothold with social engineering via a crafted HTML page. The flaw is classified CWE-863 (Incorrect Authorization), meaning the browser's Core incorrectly validates authorization checks across origins under this specific post-compromise condition. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two simultaneous conditions: first, the attacker must have already compromised the Chrome renderer process through a separate, independent vulnerability - this is a mandatory precondition, not an optional path. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS of 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N) warrants scrutiny: the AC:L and PR:N metrics are inconsistent with the description, which explicitly requires a prior renderer compromise - a high-complexity precondition that AC:L does not reflect. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later via the stable channel; this is the vendor-released patch confirmed by both the Chrome Releases advisory and EUVD-2026-65835. … Detailed patch versions, workarounds, and compensating controls in full report. |
