Security readout for executives and security teams
CVE-2011-5278 is a SQL injection issue in signature.php of Advanced Forum Signatures (afsignatures) 2.0.4 for MyBB. If an affected forum still runs this plugin, a remote attacker may manipulate database queries through afs_bar_right, risking data exposure or site compromise. Sources do not provide CVSS, patch, or active exploitation evidence. Exposure is likely limited to legacy MyBB sites with the Advanced Forum Signatures plugin installed, especially version 2.0.4. The provided affected-product metadata is incomplete, so asset confirmation must come from plugin inventory, file review, or application owner validation. Prioritize remediation for any internet-facing MyBB forum still using this plugin. The vulnerability is old, but legacy plugins often remain forgotten, and SQL injection can threaten user data and site integrity. If the plugin is not present, no direct exposure is indicated by the provided sources. Mitigation focus: Identify MyBB installations and confirm whether afsignatures is installed.; Disable or remove the plugin if it is unused or unmaintained.; Check vendor or maintainer guidance for any fixed release..
