Opera before 12.10 does not properly handle incorrect size data in a WebP image, which allows remote attackers to obtain potentially sensitive information from process memory by using a crafted image as the fill pattern for a canvas.

Security readout for executives and security teams

This is a legacy Opera browser information-disclosure flaw. A malicious webpage could use a crafted WebP image in a canvas pattern to expose potentially sensitive process memory. The provided sources do not show active exploitation or a CVSS score. Exposure is most likely limited to endpoints still running Opera versions before 12.10 and browsing attacker-controlled or compromised web content. Current browser fleets are unlikely affected unless legacy Opera remains installed. Treat this as a legacy-browser cleanup issue, not an emergency, unless vulnerable Opera versions are still in use. Business urgency rises where users browse untrusted sites with obsolete Opera builds. Mitigation focus: Identify and remove Opera versions before 12.10 from managed endpoints.; Upgrade legacy Opera installations to 12.10 or later where still required.; Check Opera vendor guidance for any environment-specific remediation notes..
