HarborGuard Analysis
Synopsis
An inappropriate implementation flaw in the ImageCapture component of Google Chrome (versions prior to 149.0.7827.53) allows a remote attacker who has already compromised the renderer process to escalate privileges by serving a crafted HTML page. The vulnerability is reachable over the network but requires victim interaction and benefits from a pre-compromised renderer, making it a chained exploit rather than a standalone entry point. Successful exploitation gives the attacker high impact across confidentiality, integrity, and availability. A patched-image rebuild at version 149.0.7827.53 is available on HarborGuard for affected environments.
HarborGuard Coverage
Detection capability for CVE-2026-11296 is available across every HarborGuard environment, with the CVE ingested from upstream feeds within minutes of publication and matched against all customer images in connected registries and CI/CD pipelines, including custom-built images that bundle Chrome or Chromium. Coverage extends to base images derived from distributions that vendor Chrome as a managed package.
AvailableHarborGuard scores this finding at CVSS 7.5 HIGH (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H) and weighs it against each customer environment's compliance policy to determine urgency. Routed findings land in the appropriate team inbox based on per-org ownership rules, so the right engineers see this without manual filtering.
AvailableA patched-image rebuild at Chrome 149.0.7827.53 is available to customers running an affected version. For customers who opt into auto-remediation, HarborGuard triggers a rebuild, runs a regression test suite against the new image, and opens a pull request against affected workloads automatically.
AvailableExploit Conditions
- Network reachabilityRequired
The attacker must reach the victim over the network by serving a crafted HTML page, making over-the-network exposure a prerequisite.
- AuthenticationNot required
No authentication is needed; the attacker does not need any account on the target system to initiate the attack.
- Victim interactionRequired
The victim must visit or interact with a crafted HTML page, introducing a social-engineering step that the attacker must clear.
- Attack complexityDetail
Attack complexity is high, meaning the attacker depends on a pre-compromised renderer process as a prerequisite condition before privilege escalation is possible.
Blast Radius
- A successful attacker reads sensitive data accessible to the elevated process, including credentials, tokens, or private user content.
- The attacker modifies data or browser state beyond normal renderer permissions, potentially altering stored settings or injecting content.
- The attacker disrupts or crashes affected browser processes, causing service loss for the victim.
How HarborGuard Handles This
Available on HarborGuard: scanning for CVE-2026-11296 runs automatically against any image that includes Chrome or Chromium prior to 149.0.7827.53. Where a customer's registry contains an affected image, a rebuild at the patched version (149.0.7827.53) is available immediately. For customers who opt into auto-remediation, HarborGuard performs the rebuild, executes regression tests, and opens a pull request against affected workloads. Median time from CVE publication to merged patch PR for high-severity issues is around 90 minutes for environments with auto-remediation enabled. Customers not yet on auto-remediation are encouraged to prioritize manual upgrade given the high CVSS impact scores across all three impact dimensions, even though the high attack complexity and required victim interaction lower the likelihood of opportunistic mass exploitation.
