Prior to version 3.0.1 of the `stable` branch and version 3.1.0.beta2 of the `beta` and `tests-passed` branches, the count of topics displayed for a tag is a count of all regular topics regardless of whether the topic is in a read restricted category or not. As a result, any users can technically poll a sensitive tag to determine if a new topic is created in a category which the user does not have excess to. In version 3.0.1 of the `stable` branch and version 3.1.0.beta2 of the `beta` and `tests-passed` branches, the count of topics displayed for a tag defaults to only counting regular topics which are not in read restricted categories. Staff users will continue to see a count of all topics regardless of the topic's category read restrictions. ## CVSS-Vektor ``` CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N ``` | Metrik | Wert | Bewertung | |---|---|---| | AV Angriffsvektor | Netzwerk | bad | | AC Komplexität | Gering | bad | | PR Privilegien | Keine | bad | | UI Interaktion | Erforderlich | good | | S Scope | Unverändert | good | | C Vertraulichkeit | Gering | warn | | I Integrität | Keine | good | | A Verfügbarkeit | Keine | good | ## Patch verfügbar (OSV) - f54d21a80b481a26fcb2dce22afe92387ac87004 (Commit) - 105fee978d73b0ec23ff814a09d1c0c9ace95164 (Commit) ## Referenzen - - - - - --- _Exportiert aus dem [tsecurity.de CVE-Dossier](https://tsecurity.de/cve?cve=CVE-2023-23622) · Datenquellen: EUVD (ENISA), NVD, OSV, CISA KEV, FIRST EPSS, Exploit-DB, BSI BITS_
