CVE-2012-1257

29
FAUCET Score

CVE-2012-1257 describes an information disclosure vulnerability in Pidgin 2.10.0, where the application uses DBUS for cleartext communication, allowing local attackers to intercept sensitive information via a dbus session monitor. This medium-severity vulnerability (CVSS 5.5) requires local access and low privileges, potentially leading to high confidentiality impact without affecting integrity or availability. While not actively exploited in the wild or on CISA's KEV catalog, an ExploitDB entry (EDB-36884) exists for a related libpurple OTR information disclosure, and there is minimal community discussion.
