CVSS: 4.3EPSS: 0%CPEs: 2EXPL: 0CVE-2022-29243 – Improper input-size validation on the user new session name in Nextcloud Server
https://notcve.org/view.php?id=CVE-2022-29243
Nextcloud Server is the file server software for Nextcloud, a self-hosted productivity platform. Prior to versions 22.2.7 and 23.0.4, missing input-size validation of new session names allows users to create app passwords with long names. These long names are then loaded into memory on usage, resulting in impacted performance. Versions 22.2.7 and 23.0.4 contain a fix for this issue. There are currently no known workarounds available. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-7cwm-qph5-4h5w https://github.com/nextcloud/server/pull/31658 https://hackerone.com/reports/1153138 https://security.gentoo.org/glsa/202208-17 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2022-24888
Nextcloud Server is the file server software for Nextcloud, a self-hosted productivity platform. Prior to versions 20.0.14.4, 21.0.8, 22.2.4, and 23.0.1, it is possible to create files and folders that have leading and trailing \n, \r, \t, and \v characters. The server rejects files and folders that have these characters in the middle of their names, so this might be an opportunity for injection. This issue is fixed in versions 20.0.14.4, 21.0.8, 22.2.4, and 23.0.1.

CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-41233 – Missing authorization in Nextcloud text
https://notcve.org/view.php?id=CVE-2021-41233
Nextcloud text is a collaborative document editing using Markdown built for the nextcloud server. Due to an issue with the Nextcloud Text application, which is by default shipped with Nextcloud Server, an attacker is able to access the folder names of "File Drop". For successful exploitation an attacker requires knowledge of the sharing link. It is recommended that users upgrade their Nextcloud Server to 20.0.14, 21.0.6 or 22.2.1. Users unable to upgrade should disable the Nextcloud Text application in the application settings. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-26c8-35cm-xq9m https://github.com/nextcloud/text/pull/1884 • CWE-862: Missing Authorization CWE-863: Incorrect Authorization •
