**Name of the Vulnerable Software and Affected Versions** Opera versions prior to 7.55 **Description** The issue is related to the improper validation of base64 encoded binary data in a data: (RFC 2397) URL. This can cause the URL to be obscured in a download dialog, potentially allowing remote attackers to trick users into executing arbitrary code. **Recommendations** For Opera versions prior to 7.55, update to version 7.55 or later to resolve the issue.

Name of the Vulnerable Software and Affected Versions: TWiki version 20030201 Description: The issue allows remote attackers to execute arbitrary commands via shell metacharacters in a search string, specifically in the search function. Recommendations: For TWiki version 20030201, consider restricting the use of the search function until a patch is available, or apply configuration changes to limit the execution of shell metacharacters in search strings.
