View online: https://www.drupal.org/sa-contrib-2026-246 Project: TinyPNG [1] Project machine name: tinypng Date: 2026-October-21 Security risk: *Moderately critical* 10 ∕ 25 AC:Complex/A:None/CI:Some/II:None/E:Theoretical/TD:Uncommon [2] Vulnerability: Information disclosure Affected versions: <2.0.2 Description: TinyPNG uses smart lossy compression techniques to reduce the file size of your PNG files. The module doesn't sufficiently check access to image style derivatives when those files are served via a file stream other than private://. This vulnerability is mitigated by the fact that Drupal must be configured to use a contributed (non-core) file scheme to serve private derived images. Solution: Install the latest version: * If you use TinyPNG 2.0.x, upgrade to TinyPNG 2.0.2 [3] Reported By: * Pierre Rudloff (prudloff) [4] of the Drupal Security Team Fixed By: * István Csáki (csakiistvan) [5] * Vince Tikász (tikaszvince) [6] Coordinated By: * Juraj Nemec (poker10) [7] of the Drupal Security Team * Pierre Rudloff (prudloff) [8] of the Drupal Security Team ------------------------------------------------------------------------------ Contribution record [9] [1] https://www.drupal.org/project/tinypng [2] https://www.drupal.org/drupal-security-team/security-risk-levels-defined [3] https://www.drupal.org/project/tinypng/releases/2.0.2 [4] https://www.drupal.org/u/prudloff [5] https://www.drupal.org/u/csakiistvan [6] https://www.drupal.org/u/tikaszvince [7] https://www.drupal.org/u/poker10 [8] https://www.drupal.org/u/prudloff [9] https://new.drupal.org/contribution-record?source_link=https%3A//www.drupal....
