From the CVE request :
Roland Becker and Damien Regad (MantisBT developers) found that any user able to report issues via the SOAP interface could also modify any bugnotes (comments) created by other users. In a default/typical MantisBT installation, SOAP API is enabled and any user can sign up to report new issues. This vulnerability therefore impacts upon many public facing MantisBT installations.
Upstream patches (against the v1.2.x branch) seems to be the
This issue affects the versions of the mantis package, as shipped with Fedora release of 15, 16, and 17. Please schedule an update.
I am not completely sure, the version of mantis package, as shipped with Fedora EPEL 5 is affected by this issue. From the upstream patches, relevant changes are touching mc_issue_note_update() routine, while that one doesn't seem to be available yet in mantis-1.1.8 version, as shipped with Fedora EPEL 5 (there are only mc_issue_note_add(), mc_issue_note_delete(), and mc_issue_update() ones [but 'note' is missing in the last one]).
But to be sure, could you please have a double-checking look at the proposed patch and situation in EPEL 5 version, and schedule a fix if necessary for EPEL 5 too (I am going to create a bug for this version too, since it's affected by the second bug 830737), so we would not miss something?
Thank you, Jan.

The CVE identifier of CVE-2012-2691 has been assigned to this issue:
mantis-1.2.12-1.fc18 has been pushed to the Fedora 18 stable repository. If problems still persist, please make note of it in this bug report.
mantis-1.2.12-1.fc16 has been pushed to the Fedora 16 stable repository. If problems still persist, please make note of it in this bug report.
mantis-1.2.12-1.fc17 has been pushed to the Fedora 17 stable repository. If problems still persist, please make note of it in this bug report.
EPEL5 hasn't been touched since Dec 2010, and the package is technically orphaned. As a result I'm closing this bug as this issue is fixed in Fedora. The EPEL5 tracking bug #800667 will remain open until either mantis is dropped from EPEL or it is fixed.
