+  * aggregate: Use LWPx::ParanoidAgent if available.
+    Previously blogspam, openid and pinger used this module if available,
+    but aggregate did not. This prevents server-side request forgery or
+    local file disclosure, and mitigates denial of service when slow
+    "tarpit" URLs are accessed.
+    (CVE-2019-9187)
+  * blogspam, openid, pinger: Use a HTTP proxy if configured, even if
+    LWPx::ParanoidAgent is installed.
+    Previously, only aggregate would obey proxy configuration. If a proxy
+    is used, the proxy (not ikiwiki) is responsible for preventing attacks
+    like CVE-2019-9187.
+  * aggregate, blogspam, openid, pinger: Do not access non-http, non-https
+    URLs.
+    Previously, these plugins would have allowed non-HTTP-based requests if
+    LWPx::ParanoidAgent was not installed. Preventing file URIs avoids local
+    file disclosure, and preventing other rarely-used URI schemes like
+    gopher mitigates request forgery attacks.
+  * aggregate, openid, pinger: Document LWPx::ParanoidAgent as strongly
+    recommended.
+    These plugins can request attacker-controlled URLs in some site
+    configurations.
+  * blogspam: Document LWPx::ParanoidAgent as desirable.
+    This plugin doesn't request attacker-controlled URLs, so it's
+    non-critical here.
+  * blogspam, openid, pinger: Consistently use cookiejar if configured.
+    Previously, these plugins would only obey this configuration if
+    LWPx::ParanoidAgent was not installed, but this appears to have been
+    unintended.
   * po: Always filter .po files.
     The po plugin in previous ikiwiki releases made the second and
     subsequent filter call per (page, destpage) pair into a no-op,
