From 9a275b2f1846d7268c71a740975447e269383849 Mon Sep 17 00:00:00 2001 From: Simon McVittie Date: Sun, 10 Feb 2019 16:56:41 +0000 Subject: doc: Document security issues involving LWP::UserAgent Recommend the LWPx::ParanoidAgent module where appropriate. It is particularly important for openid, since unauthenticated users can control which URLs that plugin will contact. Conversely, it is non-critical for blogspam, since the URL to be contacted is under the wiki administrator's control.
