The localization functionality in TWiki before 5.1.3, and Foswiki 1.0.x through 1.0.10 and 1.1.x through 1.1.6, allows remote attackers to cause a denial of service (memory consumption) via a large integer in a %MAKETEXT% macro.

Cross-site request forgery (CSRF) vulnerability in Foswiki before 1.0.5 allows remote attackers to hijack the authentication of arbitrary users for requests that modify pages, change permissions, or change group memberships, as demonstrated by a URL for a (1) save or (2) view script in the SRC attribute of an IMG element, a related issue to CVE-2009-1339.
