Vulnerabilities

Net::SAML2 versions before 0.86 for Perl allow authentication bypass because _verify_encrypted_assertion accepts an EncryptedAssertion whose decrypted content carries no signature. _verify_encrypted_assertion decrypts the EncryptedAssertion and returns it as verified when it carries no signature, via "return $xml unless $xpath->exists('dsig:Signature', $assert);". The signature check and the trust anchor check that follow run only when a signature is present, so a decrypted assertion with no dsig:Signature element reaches new_from_xml unverified and its NameID and attributes are read into the assertion object. An SP's encryption certificate is published in its SAML metadata so the IdP can encrypt to it, so any party can encrypt an unsigned assertion to that certificate, wrap it in a samlp:Response, and post it to the assertion consumer service. Any caller that configures a decryption key_file, and so accepts EncryptedAssertions, takes identity fields from an assertion that no trust anchor covers, and an unauthenticated party can authenticate as an arbitrary user. Callers with no key_file configured do not decrypt and are unaffected.

Improperly Controlled Modification of Dynamically-Determined Object Attributes vulnerability in Drupal Formatter Field allows Object Injection. This issue affects Formatter Field versions: from 0.0.0 to 2.0.0.

ImageMagick before 7.1.2-15 and 6.9.13-40 contains a command injection vulnerability in the SVG decoder that allows attackers to inject arbitrary MVG drawing commands. Attackers can craft malicious SVG files with injected Magick Vector Graphics commands that execute during rendering.

Joomlic's iCagenda event-management extension for Joomla contains an unrestricted file-upload flaw (CWE-434) in its file attachment feature, exploitable over the network without authentication or user interaction (CVSS 4.0 score 10.0). Because the extension accepts arbitrary file types, an attacker can upload a malicious PHP file through the attachment feature and have the web server execute it as PHP code. Successful exploitation gives unauthenticated attackers remote code execution on the affected Joomla site, which typically leads to full site or web-server compromise. Any Joomla installation running the iCagenda extension is affected; the available advisory data specifies no affected or fixed version range, so no version numbers can be stated. The flaw is being exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-07-10 (reportedly exploited as a zero-day, with ransomware use currently unknown), public proof-of-concept code is available, and EPSS assigns roughly a 20% probability of exploitation within 30 days.

Do: Joomla administrators running iCagenda should update to the latest release published by Joomlic (no specific fixed version is stated in the available data) and, per the KEV required action, apply vendor mitigations in accordance with CISA BOD 26-04, prioritizing internet-exposed instances. Until patched, restrict or disable the file-attachment upload feature (e.g., prevent PHP execution/uploads in the attachments directory) and review web server logs and upload directories for unexpected .php files indicating prior compromise. Given confirmed in-the-wild exploitation reportedly predating disclosure, assume potential compromise and follow CISA's forensics triage requirements where applicable.
