CVE-2023-27533 (GCVE-0-2023-27533)

Vulnerability from cvelistv5 – Published: 2023-03-30 00:00 – Updated: 2026-02-13 20:09
VLAI
Summary
A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and "telnet options" during server negotiation. The lack of proper input scrubbing allows an attacker to send content or perform option negotiation without the application's intent. This vulnerability could be exploited if an application allows user input, thereby enabling attackers to execute arbitrary code on the system.

Title
Calculated Fields Form <= 5.2.45 - HTML Injection
Summary
The Calculated Fields Form plugin for WordPress is vulnerable to HTML Injection in all versions up to, and including, 5.2.45. This is due to the plugin not properly neutralizing HTML elements from submitted forms. This makes it possible for unauthenticated attackers to inject arbitrary HTML that will render when the administrator views form submissions in their email.

5.3 (Medium)

CVE-2025-61911 (GCVE-0-2025-61911)

Title
python-ldap has sanitization bypass in ldap.filter.escape_filter_chars
Summary
python-ldap is a lightweight directory access protocol (LDAP) client API for Python. In versions prior to 3.4.5, the sanitization method `ldap.filter.escape_filter_chars` can be tricked to skip escaping of special characters when a crafted `list` or `dict` is supplied as the `assertion_value` parameter, and the non-default `escape_mode=1` is configured. The method `ldap.filter.escape_filter_chars` supports 3 different escaping modes. `escape_mode=0` (default) and `escape_mode=2` happen to raise exceptions when a `list` or `dict` object is supplied as the `assertion_value` parameter. However, `escape_mode=1` computes without performing adequate logic to ensure a fully escaped return value. If an application relies on the vulnerable method in the `python-ldap` library to escape untrusted user input, an attacker might be able to abuse the vulnerability to launch ldap injection attacks which could potentially disclose or manipulate ldap data meant to be inaccessible to them. Version 3.4.5 fixes the issue by adding a type check at the start of the `ldap.filter.escape_filter_chars` method to raise an exception when the supplied `assertion_value` parameter is not of type `str`.

Title
Leaf-kit html escaping does not work on characters that are part of extended grapheme cluster
Summary
Leafkit is a templating language with Swift-inspired syntax. Prior to 1.4.1, htmlEscaped in leaf-kit will only escape html special characters if the extended grapheme clusters match, which allows bypassing escaping by using an extended grapheme cluster containing both the special html character and some additional characters. In the case of html attributes, this can lead to XSS if there is a leaf variable in the attribute that is user controlled. This vulnerability is fixed in 1.4.1.

CVE-2026-29042 (GCVE-0-2026-29042)

Vulnerability from cvelistv5 – Published: 2026-03-06 06:57 – Updated: 2026-03-09 19:57

Title
Nuclio Shell Runtime Command Injection Leading to Privilege Escalation
Summary
Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.15.20, the Nuclio Shell Runtime component contains a command injection vulnerability in how it processes user-supplied arguments. When a function is invoked via HTTP, the runtime reads the X-Nuclio-Arguments header and directly incorporates its value into shell commands without any validation or sanitization. This issue has been patched in version 1.15.20.
Severity
8.9 (High)

Mitigation

Phase: Requirements

Description:

  • Programming languages and supporting technologies might be chosen which are not subject to these issues.
Mitigation

Phase: Implementation

Description:

  • Utilize an appropriate mix of allowlist and denylist parsing to filter special element syntax from all input.
CAPEC-81: Web Server Logs Tampering

Web Logs Tampering attacks involve an attacker injecting, deleting or otherwise tampering with the contents of web logs typically for the purposes of masking other malicious behavior. Additionally, writing malicious data to log files may target jobs, filters, reports, and other agents that process the logs in an asynchronous attack pattern. This pattern of attack is similar to "Log Injection-Tampering-Forging" except that in this case, the attack is targeting the logs of the web server and not the application.

CAPEC-93: Log Injection-Tampering-Forging

This attack targets the log files of the target host. The attacker injects, manipulates or forges malicious log entries in the log file, allowing them to mislead a log audit, cover traces of attack, or perform other malicious actions. The target host is not properly controlling log access. As a result tainted data is resulting in the log files leading to a failure in accountability, non-repudiation and incident forensics capability.
