Prior to 7.0.2, summary In Zammad&#8217;s inbound PGP email processing, the return value of the gpg verification call was silently discarded. Regardless of whether gpg reported a valid, invalid, or missing signature, the handler unconditionally wrote sign: { success: true, comment: &#8220;Good signature&#8221; } to the article&#8217;s security preferences. Impact Any sender could tamper with the body of a multipart\/signed PGP email, or craft a message with an entirely fabricated or mismatched signature, and Zammad would display it to the recipient as cryptographically verified with a &#8220;Good signature&#8221; label. Users and agents relying on Zammad&#8217;s signature indicator to confirm message authenticity and integrity would be misled into trusting modified or forged content. The vulnerability affects all inbound PGP-signed emails processed while the PGP integration is enabled.
