When the freeURL feature is enabled (by setting the `allowFreeURL` config option or the `CMD_ALLOW_FREEURL` environment variable to `true`), any user with the appropriate permissions can create a note with an arbitrary alias, e.g. by accessing it in the browser. When MySQL or MariaDB are used, it is possible to create a new note with an alias that matches the lower-cased ID of a different note.

Depending on the permission settings of the HedgeDoc instance, the issue can be exploited only by logged-in users or by all (including non-logged-in) users. The exploit requires knowledge of the ID of the target note. Attackers could use this issue to present a manipulated copy of the original note to the user, e.g. by replacing the links with malicious ones. Attackers can also use this issue to prevent access to the original note, causing a denial of service. No data is lost, as the original content of the affected notes is still present in the database. Users are advised to upgrade to version 1.10.0 which addresses this issue. Users unable to upgrade may disable freeURL mode which prevents the exploitation of this issue.

Al utilizar HedgeDoc 1 con MySQL o MariaDB, es posible crear notas con un alias que coincida con el ID de las notas existentes. A partir de ese momento, ya no se puede acceder a la nota existente afectada y la nueva la oculta de manera efectiva. Cuando se habilita la funci\u00f3n freeURL (estableciendo la opci\u00f3n de configuraci\u00f3n `allowFreeURL` o la variable de entorno `CMD_ALLOW_FREEURL` en `true`), cualquier usuario con los permisos adecuados puede crear una nota con un alias arbitrario, por ejemplo, accediendo a ella en el navegador. Cuando se utiliza MySQL o MariaDB, es posible crear una nueva nota con un alias que coincida con el ID en min\u00fasculas de una nota diferente. Luego, HedgeDoc siempre presenta la nueva nota a los usuarios, ya que estas bases de datos realizan una comparaci\u00f3n sin distinguir entre may\u00fasculas y min\u00fasculas y el alias en min\u00fasculas se encuentra primero. Este problema solo afecta a las instancias de HedgeDoc que utilizan MySQL o MariaDB. Seg\u00fan la configuraci\u00f3n de permisos de la instancia de HedgeDoc, el problema puede ser explotado solo por usuarios que hayan iniciado sesi\u00f3n o por todos los usuarios (incluidos los que no hayan iniciado sesi\u00f3n). El exploit requiere el conocimiento del ID de la nota de destino. Los atacantes podr\u00edan usar este problema para presentar una copia manipulada de la nota original al usuario, por ejemplo, reemplazando los enlaces con enlaces maliciosos. Los atacantes tambi\u00e9n pueden usar este problema para evitar el acceso a la nota original, lo que provoca una denegaci\u00f3n de servicio. No se pierden datos, ya que el contenido original de las notas afectadas a\u00fan est\u00e1 presente en la base de datos. Se recomienda a los usuarios que actualicen a la versi\u00f3n 1.10.0 que soluciona este problema. Los usuarios que no puedan actualizar pueden desactivar el modo freeURL que evita la explotaci\u00f3n de este problema. El impacto tambi\u00e9n se puede limitar restringiendo la creaci\u00f3n de notas freeURL a usuarios confiables que hayan iniciado sesi\u00f3n habilitando `requireFreeURLAuthentication`/`CMD_REQUIRE_FREEURL_AUTHENTICATION`.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:L\",\"baseScore\":6.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"LOW\"},\"exploitabilityScore\":2.2,\"impactScore\":4.2}]},\"weaknesses\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-1289\"}]}],\"references\":[{\"url\":\"https://github.com/hedgedoc/hedgedoc/commit/380587b7fd65bc1eb71eef51a3aab324f9877650\",\"source\":\"security-advisories@github.com\"},{\"url\":\"https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-pjf2-269h-cx7p\",\"source\":\"security-advisories@github.com\"}]}}"
