Summary
LogTape before versions 1.3.11, 2.0.14, and 2.1.5 has a vulnerability in the @logtape/syslog package that allows injection of forged syslog records. The escapeStructuredDataValue() function does not neutralize control characters, and formatStructuredData() does not validate keys, enabling manipulation of frames and data elements.
Risk Assessment
An attacker can send forged syslog records with arbitrary hosts, applications, processes, undermining the integrity of collectors and SIEM systems.
Recommendation
Update LogTape to version 1.3.11, 2.0.14, or 2.1.5. Additionally, validate input data before forwarding to syslog.

- CVE-2026-118636Critical
The JavaNativeMessageDecoder class in the Apache MINA 3.0 codec module calls ObjectInputStream.readObject() on frame bytes without any class filter. An application that places it in front of an untrusted peer is exposed to gadget-chain remote code execution. The 3.0.0 branch is inactive and no fix will be released for it.
- CVE-2026-120209Critical
AJ-Report through 1.7.1 signs share tokens with a hard-coded JWT secret, allowing attackers to forge valid Share-Tokens offline. Attackers can mint a token with reportCode 'dataSet' to access the testTransform endpoint, which passes scripts to GroovyClassLoader for unauthenticated remote code execution.
- CVE-2026-120201Critical
Jpom 2.10.0 through 2.11.12 contains an authentication bypass vulnerability that allows unauthenticated attackers to gain super-administrator access by injecting query conditions into the JPOM-USER-TOKEN header. Attackers can send a value like 'is not null', which Hutool's Condition parser treats as an operator, then execute commands through Jpom's script features.
- CVE-2026-118235Critical
The SimpleForm plugin for WordPress (versions up to and including 3.10.2) is vulnerable to arbitrary file upload via the handle_upload function. Missing a server-side file key allowlist and pre-sanitization extension derivation allows a trailing-dot filename to bypass all extension and MIME validation, enabling unauthenticated attackers to upload executable files and achieve remote code execution. The only access control is a nonce printed into every public form's data-nonce attribute, trivially obtainable by any unauthenticated visitor.
- CVE-2026-103882Critical
The Acadlix LMS plugin for WordPress (versions up to and including 1.1.9) is vulnerable to arbitrary file deletion due to insufficient file path validation in the post_delete_assessment_file_by_id function. Authenticated attackers with subscriber-level access or higher can delete arbitrary files on the server, potentially leading to remote code execution when critical files such as wp-config.php are deleted. The route's permission callback only verifies a generic wp_rest nonce emitted in the public acadlixOptions JavaScript object on every frontend page, effectively reducing the authentication requirement to unauthenticated.
Original NVD description (English source)
LogTape is an unobtrusive logging library. Prior to 1.3.11, 2.0.14, and 2.1.5, the @logtape/syslog package's escapeStructuredDataValue() function in packages/syslog/src/syslog.ts does not neutralize C0 control characters from U+0000 through U+001F in structured data values, and formatStructuredData() inserts property keys without validating the RFC 5424 SD-NAME grammar. When includeStructuredData is true, an attacker-controlled newline can terminate an RFC 6587 non-transparent TCP syslog frame and make following bytes appear as a forged RFC 5424 record, while a key containing a closing bracket or other forbidden character can terminate or corrupt the structured-data element. Applications that forward attacker-controlled property values or keys can therefore allow forged records with arbitrary hosts, applications, process identifiers, facilities, or severity levels, undermining downstream collector and SIEM integrity. This issue is fixed in versions 1.3.11, 2.0.14, and 2.1.5.
