9.8	CVE-2023-26477 XWiki Platform is a generic wiki platform. Starting in versions 6.3-rc-1 and 6.2.4, it's possible to inject arbitrary wiki syntax including Groovy, Python and Velocity script macros via the `newThemeName` request parameter (URL parameter), in combination with additional parameters. This has been patched in the supported versions 13.10.10, 14.9-rc-1, and 14.4.6. As a workaround, it is possible to edit `FlamingoThemesCode.WebHomeSheet` and manually perform the changes from the patch fixing the issue. Published Thursday, March 2, 2023
8.1	CVE-2023-26478 XWiki Platform is a generic wiki platform. Starting in version 14.3-rc-1, `org.xwiki.store.script.TemporaryAttachmentsScriptService#uploadTemporaryAttachment` returns an instance of `com.xpn.xwiki.doc.XWikiAttachment`. This class is not supported to be exposed to users without the `programing` right. `com.xpn.xwiki.api.Attachment` should be used instead and takes case of checking the user's rights before performing dangerous operations. This has been patched in versions 14.9-rc-1 and 14.4.6. There are no known workarounds for this issue. Published Thursday, March 2, 2023
6.5	CVE-2023-26479 XWiki Platform is a generic wiki platform. Starting in version 6.0, users with write rights can insert well-formed content that is not handled well by the parser. As a consequence, some pages becomes unusable, including the user index (if the page containing the faulty content is a user page) and the page index. Note that on the page, the normal UI is completely missing and it is not possible to open the editor directly to revert the change as the stack overflow is already triggered while getting the title of the document. This means that it is quite difficult to remove this content once inserted. This has been patched in XWiki 13.10.10, 14.4.6, and 14.9-rc-1. A temporary workaround to avoid Stack Overflow errors is to increase the memory allocated to the stack by using the `-Xss` JVM parameter (e.g., `-Xss32m`). This should allow the parser to pass and to fix the faulty content. The consequences for other aspects of the system (e.g., performance) are unknown, and this workaround should be only be used as a temporary solution. The workaround does not prevent the issue occurring again with other content. Consequently, it is strongly advised to upgrade to a version where the issue has been patched.

5.4	CVE-2023-26480 XWiki Platform is a generic wiki platform. Starting in version 12.10, a user without script rights can introduce a stored cross-site scripting by using the Live Data macro. This has been patched in XWiki 14.9, 14.4.7, and 13.10.10. There are no known workarounds. Published Thursday, March 2, 2023
N/A	CVE-2021-36689 An issue discovered in com.samourai.wallet.PinEntryActivity.java in Streetside Samourai Wallet 0.99.96i allows attackers to view sensitive information and decrypt data via a brute force attack that uses a recovered samourai.dat file. The PIN is 5 to 8 digits, which may be insufficient in this situation. Published Saturday, March 4, 2023
N/A	CVE-2023-1191 A vulnerability classified as problematic has been found in fastcms. This affects an unknown part of the file admin/TemplateController.java of the component ZIP File Handler. The manipulation leads to path traversal. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The associated identifier of this vulnerability is VDB-222363. Published Monday, March 6, 2023

This vulnerability affects unknown code of the file src/at/hgz/vocabletrainer/VocableTrainerProvider.java. The manipulation leads to path traversal. Attacking locally is a requirement. Upgrading to version 1.3.1 is able to address this issue. The name of the patch is accf6838078f8eb105cfc7865aba5c705fb68426. It is recommended to upgrade the affected component.

N/A	CVE-2023-26464 UNSUPPORTED WHEN ASSIGNED When using the Chainsaw or SocketAppender components with Log4j 1.x on JRE less than 1.7, an attacker that manages to cause a logging entry involving a specially-crafted (ie, deeply nested) hashmap or hashtable (depending on which logging component is in use) to be processed could exhaust the available memory in the virtual machine and achieve Denial of Service when the object is deserialized. This issue affects Apache Log4j before 2. Affected users are recommended to update to Log4j 2.x. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
