Security readout for executives and security teams
CVE-2008-4891 is a cross-site scripting flaw in Planetluc SignMe. A vulnerable site could let an attacker inject script or HTML through the hash parameter, potentially affecting users who visit crafted pages. The public record does not show active exploitation or a severity score. Exposure is likely limited to legacy websites still running Planetluc SignMe 1.5 or earlier, especially public instances exposing signme.inc.php. The provided affected-product metadata is incomplete, so confirmation requires local software inventory or file-level review. Prioritize if any public site still uses this legacy SignMe component. The business risk is user compromise through the trusted website, but urgency is lower without evidence of active exploitation or broad modern deployment. Mitigation focus: Check whether Planetluc SignMe is deployed and identify its version.; Upgrade SignMe to version 1.55 or later where applicable.; If upgrade is unavailable, remove or disable the affected component..
