**Name of the Vulnerable Software and Affected Versions** Server Status (affected versions not specified) **Description** A problematic issue has been found in Server Status, affecting the component HTTP Status/SMTP Status. This issue leads to cross-site scripting and can be initiated remotely. The exploit has been disclosed to the public. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** PlantUML version 6.43 **Description** A vulnerability was found in the Database Information Macro component, which can be exploited to lead to cross-site scripting. The attack can be launched remotely. **Recommendations** For version 6.43, consider disabling the Database Information Macro component until a patch is available. Restrict access to the component to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Refined Toolkit (affected versions not specified) **Description** A problematic issue was found in Refined Toolkit, affecting some unknown functionality of the component UI-Image/UI-Button. This issue leads to cross site scripting and can be exploited remotely. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linking (affected versions not specified) **Description** A problematic vulnerability has been found in Linking, affecting an unknown part of the New Windows Macro component. This issue leads to cross-site scripting and can be initiated remotely. The exploit has been disclosed to the public and may be used. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Countdown Timer (affected versions not specified) **Description** A problematic issue was found in the Macro Handler component, leading to cross-site scripting. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** mruby version 1.4.1 **Description** The issue concerns a signed integer overflow in the CHECK macro within the mrbgems/mruby-sprintf/src/sprintf.c file of mruby. This overflow could potentially lead to out-of-bounds memory access due to the mrb str resize function in string.c not checking for negative lengths. **Recommendations** For mruby version 1.4.1, consider applying a patch or fix that addresses the signed integer overflow in the CHECK macro to prevent potential out-of-bounds memory access. As a temporary workaround, restrict the use of the mrb str resize function to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** mruby version 1.4.1 **Description** A heap-based buffer over-read issue was found, associated with OP ENTER, due to the failure of mrbgems/mruby-fiber/src/fiber.c to extend the stack when handling many arguments to fiber. **Recommendations** For mruby version 1.4.1, at the moment, there is no information about a newer version that contains a fix for this issue.

**Name of the Vulnerable Software and Affected Versions** mruby version 1.4.1 **Description** An issue was discovered in mruby. There is a NULL pointer dereference in `mrb class real` because `class BasicObject` is not properly supported in class.c. **Recommendations** For mruby version 1.4.1, at the moment, there is no information about a newer version that contains a fix for this issue.

**Name of the Vulnerable Software and Affected Versions** mruby version 1.4.1 **Description** The issue is related to the init copy function in kernel.c, which makes initialize copy calls for TT ICLASS objects. This allows attackers to cause a denial of service, resulting in an uninitialized pointer and application crash, or possibly have other unspecified impacts. **Recommendations** For mruby version 1.4.1, consider disabling the init copy function in kernel.c as a temporary workaround until a patch is available. Restrict access to TT ICLASS objects to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.

Name of the Vulnerable Software and Affected Versions: mruby versions prior to 1.4.1 Description: The issue is related to an integer overflow in the `mrb vm exec()` function when handling `OP GETUPVAR` in the presence of deep scope nesting, resulting in a use-after-free. This could allow an attacker who can cause Ruby code to be run to possibly execute arbitrary code. Recommendations: For versions prior to 1.4.1, update to version 1.4.1 or later to resolve the issue.
