MITRE ATT&CK
2 techniques across 2 tactics: Execution, Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires (1) a pre-existing compromise of the Chrome renderer process - the attacker must already be executing code inside the sandbox via a separate renderer bug, as explicitly stated in the CVE description; (2) the victim must load a crafted HTML page in a vulnerable Chrome version (UI:R user interaction), specifically content that exercises the Read Anything code path; and (3) the target must be running Chrome prior to 149.0.7827.103. Limiting factors: high attack complexity (AC:H) reflecting heap-grooming and timing requirements typical of use-after-free exploitation, the hard prerequisite of a chained renderer exploit (this is not a one-shot drive-by), and the requirement that the Read Anything feature be reachable in the target build. No authentication is required at the network layer (PR:N), consistent with web-delivered attacks. |
| Impact | The CVSS 8.3 vector (AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H) reflects high complexity, required user interaction (visiting a malicious page), changed scope (sandbox escape), and full CIA impact - consistent with a second-stage browser exploit. There is no KEV listing and no public POC identified, and EPSS data is not provided in the input, so this should be treated as a high-severity patch-soon issue rather than an actively-exploited emergency. The key caveat is that exploitation explicitly requires a prior renderer compromise, meaning real-world risk depends on an attacker also possessing a separate renderer RCE primitive; in a chained 1-day or 0-day scenario this becomes a critical escalator, but standalone it is not directly exploitable from a web page. No conflicting signals were observed between the description and CVSS vector. |
| Exploit ScenarioDerived | An attacker first lands a separate renderer-process RCE (via a prior 0-day or chained N-day) when a victim visits a malicious or compromised website; once code is executing inside the sandboxed renderer, the attacker triggers the Read Anything use-after-free with a crafted HTML page to corrupt heap state and pivot out of the sandbox into a more privileged Chrome process. With sandbox escape achieved, the attacker can read arbitrary user files, install persistence, and operate with the privileges of the Chrome user. No public exploit has been identified at time of analysis. |

Sandbox escape in Google Chrome versions prior to 149.0.7827.103 allows remote attackers who have already compromised the renderer process to break out of the sandbox via a use-after-free in the Read Anything component when processing a crafted HTML page. Google rates this Chromium-severity High, and no public exploit has been identified at time of analysis, but the CVSS 8.3 score reflects the severity of full sandbox escape leading to scoped impact beyond the renderer. This is a second-stage bug requiring chaining with a renderer compromise, not a one-shot drive-by.
RemediationAI
Vendor-released patch: Google Chrome 149.0.7827.103 - update Chrome via Help > About Google Chrome and relaunch the browser, or push the update through enterprise management (Chrome Browser Cloud Management, Group Policy auto-update). Refer to the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html and the upstream bug tracker entry at https://issues.chromium.org/issues/517607902. For downstream Chromium browsers, apply vendor updates as soon as they ship the merged fix. If immediate patching is not possible, compensating controls include disabling the Read Anything / reading-mode feature via enterprise policy where supported (trade-off: loss of accessibility functionality for users who rely on it), and restricting browsing to known-good sites via web filtering to reduce exposure to crafted HTML payloads (trade-off: operational friction, no protection against compromised legitimate sites).

Technical ContextAI · show details
The flaw is a CWE-416 (Use After Free) memory corruption issue in Chrome's Read Anything feature, an accessibility/reading-mode component that processes page content in the renderer process to extract readable text. Use-after-free conditions occur when freed heap memory is later dereferenced, enabling attackers to control object layout and hijack execution flow. Because this bug lives in code reachable across the renderer-to-broker IPC boundary, exploitation can transition control from the sandboxed renderer to a higher-privileged Chrome process, which is the explicit sandbox escape primitive described. Affected component is Chromium-based Google Chrome desktop builds before 149.0.7827.103.

Use after free in Read Anything in Google Chrome prior to 149.0.7827.103 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
Executive ViewAI
Google Chrome versions prior to 149.0.7827.103 contain a high-severity vulnerability (CVE-2026-11692, CVSS 8.3) enabling attackers to bypass Chrome sandbox protections and access system resources. While no public exploit identified at time of analysis, the vulnerability requires all Chrome deployments to patch immediately to prevent potential attacks. Organizations must prioritize remediation to maintain endpoint security posture.
Apply vendor patch.

SSVC AssessmentENISA
Priority Score
Attack Technique
Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
