+ * 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.
