Security/vulnerability reports should not be submitted through GitHub tickets or the public mailing lists, but instead please send your report to the email address: mapserver-security nospam @ osgeo.org (remove the blanks and ‘nospam’).

Please follow the general guidelines for bug submissions, when describing the vulnerability (see https://mapserver.org/development/bugs.html).

The MapServer PSC (Project Steering Committee) will release patches for security vulnerabilities for the last release branch of the two most recent release series (such as 8.x, 7.x. 6.x, etc...). Patches will only be provided for a period of three years from the release date of the current series. For example, as 8.0 has been released, now only 8.0.x and 7.6.x will be supported/patched and 7.6.x will only be supported for three years from the date of the 8.0 series release.

Currently, the following versions are supported:

Note: MapServer 8.0.0 was released on 2022-09-12. Note: MapServer 7.0.0 was released on 2015-07-24.

version x.y.z means:

x

• Major release series number.
• Major releases indicate substantial changes to the software and backwards compatibility is not guaranteed across series. Current release series is 8.

y

• Minor release series number.
• Minor releases indicate smaller, functional additions or improvements to the software and should be generally backwards compatible within a major release series. Users should be able to confidently upgrade from one minor release to another within the same release series, so from 7.4.x to 7.6.x.

z

• Point release series number.
• Point releases indicate maintenance releases - usually a combination of bug and security fixes and perhaps small feature additions. Backwards compatibility should be preserved and users should be able to confidently upgrade between point releases within the same release series, so from 7.6.4 to 7.6.5.
