Exploitation Conditions

Requires user interaction: a Chrome desktop user running a version earlier than 154.0.8037.57 must visit or interact with an attacker-controlled/malicious web page (UI:R). No authentication or elevated privileges are needed (PR:N), and no special or non-default Chrome configuration is indicated. Exploitation is limited by the need to drive a victim to the malicious content and by the availability of the vendor patch (154.0.8037.57 and later are not affected). The precise triggering feature cannot be pinned down because the CVE description is absent and the CWE-352 label appears inconsistent with the stated impact.

Impact

Signals are mixed and partly thin. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H = 8.8 High) describes a network-reachable, low-complexity, unauthenticated flaw that requires user interaction (a victim visiting a malicious page) and yields full compromise of the browser's confidentiality, integrity, and availability. No EPSS score, no CISA KEV listing, and no public POC were provided, so there is no evidence of active or imminent exploitation - this is 'no public exploit identified at time of analysis.' The 8.8 rating is therefore driven by the technical impact and browser attack surface, not by observed exploitation. One genuine anomaly must be stated explicitly: the CWE is CWE-352 (Cross-Site Request Forgery), yet CSRF alone almost never produces C:H/I:H/A:H on the browser itself - this combination suggests either a mislabeled root cause or a web-platform/security-UI bug that Google's tracker grouped under CSRF; verify the true class against the Chromium issue (511791538) before treating it as classic CSRF. Also note the entire description is absent, so impact wording is inferred purely from the CVSS vector. Net: a real patch-now priority because of Chrome's ubiquity and the high impact, but not an emergency in the absence of exploitation signals.

Exploit ScenarioDerived

An attacker hosts or injects a malicious web page and lures a Chrome desktop user (before 154.0.8037.57) to visit it. When the page loads, it triggers the flaw - nominally a cross-site request forgery / cross-origin state-change condition - resulting in compromise of browser-held data and process integrity without any credentials on the attacker's part. No public proof-of-concept was identified at the time of analysis.

AnalysisAIv2 – Sep 30, 2026

Cross-site request forgery in Google Chrome on desktop lets a remote, unauthenticated attacker achieve high confidentiality, integrity and availability impact against a victim who is persuaded to visit or interact with an attacker-controlled page (CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, base 8.8). Only Chrome installations older than 154.0.8037.57 are affected, and Google has shipped a stable channel fix in that build, with the issue tracked upstream as Chromium issue 511791538 and Ubuntu listed among the reporters. No public exploit code has been identified and the flaw is not in CISA KEV, but note that the official description is empty and the CWE-352 label is hard to reconcile with the full C/I/A impact claimed, so the exact triggering feature remains unconfirmed.

Earlier versions of this analysis (1)
v1 Sep 24, 2026 - 02:50

Google Chrome desktop on the stable channel is the subject of an unspecified security fix documented in a Chrome Releases stable-channel update, but no description, CVSS score or vector, and no CWE are available from any of the provided sources, making this a data-void CVE whose severity and attack path cannot be characterized. The only concrete signal in the intelligence set is that a vendor fix has shipped and that Canonical (vendor:ubuntu) is tracking it against the Ubuntu-packaged Chrome build, so anything beyond "a fix was released" is inference rather than confirmed fact. No CISA KEV entry and no public exploit code were identified at time of analysis, and no EPSS score was provided, so there is no evidence of active exploitation in the supplied data.

RemediationAI

Vendor-released patch: Google Chrome 154.0.8037.57, distributed through the stable channel update documented at http://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0856730748.html, with the underlying defect tracked at https://issues.chromium.org/issues/511791538; upgrade to 154.0.8037.57 or later and confirm the running build via chrome://version, then fully restart the browser so the new binary is loaded (Chromium/Ubuntu users should also refresh the packaged build, since Ubuntu is named as a reporter and its Chromium packages lag upstream releases). Because Google's advisory is the only authoritative description and the CVE text is empty, no feature-level workaround can be recommended with confidence; the practical compensating controls are to enforce the update through Chrome Enterprise update policies or your software-management tooling, to verify fleet-wide version compliance, and, in the interim, to reduce exposure of unpatched endpoints by restricting browsing to trusted internal sites and applying network-level filtering or isolation for untrusted web content. Note the trade-offs: soft-blocking untrusted sites degrades usability, content isolation adds latency and licensing cost, and disabling an unknown feature is not actionable until the affected component is identified - none of these substitute for the 154.0.8037.57 upgrade, and no vendor-released standalone mitigation other than the patch is identified in the source data.

Technical ContextAI · show details

The record carries CWE-352 (cross-site request forgery), a class of flaw in which an application fails to verify that a state-changing request originated from an expected origin or that a per-session token/state value was supplied, letting a hostile page cause the victim's browser to issue privileged requests with the victim's ambient authority. In a browser product such as Chrome this typically means the attacker page can drive privileged operations in the browser context (or trick the browser into acting on behalf of the victim site) because origin or state validation was missing on one specific code path. The data here is partly thin: no CPE strings are supplied, and the EUVD affected-version string is malformed ("Chrome 154.0.8037.57 <154.0.8037.57"), which should be read as "Chrome builds prior to 154.0.8037.57". The vulnerability entry is cross-referenced from the Google Chrome Releases stable channel update, NVD, and the Chromium issue tracker (issues.chromium.org/issues/511791538), with ENISA EUVD ID EUVD-2026-89255. Because the CVE description is absent, the specific component or feature cannot be pinned down, and the CWE-352 classification sits awkwardly alongside the stated PR:N/UI:R vector with high confidentiality, integrity and availability impact, so the practical attack path should be treated as unverified rather than assumed to be a classic cookie-based CSRF.

Executive ViewAI

Why It Matters

Google Chrome desktop versions prior to 154.0.8037.57 are affected by a high-severity cross-site request forgery vulnerability that can result in high confidentiality, integrity, and availability impact when a user interacts with an attacker-controlled page. No public exploit code has been identified at time of analysis and the issue is not in CISA KEV, but the broad enterprise deployment of Chrome and the vendor-released fix make timely update the primary risk-reduction step. Leadership should care because unpatched endpoints could be manipulated to expose, alter, or disrupt data under a user's browser context.
