Information leak in ControlledFrame in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to obtain sensitive information via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
ControlledFrame in Google Chrome prior to 153.0.8010.36 exposes sensitive information to an attacker who has already achieved renderer process compromise, exploitable via a crafted HTML page (UI:R). This is a chained post-exploitation primitive rather than an initial access vector: it extends the damage of a separate renderer exploit by enabling cross-origin data exfiltration from the victim's session. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two chained conditions: (1) The attacker must have already achieved code execution within Chrome's renderer process via a separate, independent vulnerability - this is a substantial prerequisite that limits the attack surface to scenarios where an active renderer exploit chain exists or is deployed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.3 (Medium) vector CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N is well-calibrated: AC:H encodes the non-trivial prerequisite of a pre-compromised renderer, UI:R reflects victim interaction with a crafted HTML page, C:H captures the potential sensitivity of ControlledFrame-accessible data, and I:N/A:N correctly reflect a read-only disclosure impact with no scope change (S:U). … 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 | Upgrade Google Chrome to version 153.0.8010.36 or later; this release is documented in the stable channel advisory at https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html and can be applied via Chrome's built-in updater or enterprise deployment (GPO, SCCM, Workspace ONE). … Detailed patch versions, workarounds, and compensating controls in full report. |
