Discourse is an open-source discussion platform. Prior to version 3.0.1 on the `stable` branch and 3.1.0.beta2 on the `beta` and `tests-passed` branches, the contents of latest/top routes for restricted tags can be accessed by unauthorized users. This issue is patched in version 3.0.1 on the `stable` branch and 3.1.0.beta2 on the `beta` and `tests-passed` branches. There are no known workarounds.
Discourse is an open-source discussion platform. Prior to version 3.0.1 on the `stable` branch and version 3.1.0.beta2 on the `beta` and `tests-passed` branches, a malicious user can cause a regular expression denial of service using a carefully crafted user agent. This issue is patched in version 3.0.1 on the `stable` branch and version 3.1.0.beta2 on the `beta` and `tests-passed` branches. There are no known workarounds.
Discourse is an open-source discussion platform. Prior to version 3.0.1 on the `stable` branch and version 3.1.0.beta2 on the `beta` and `tests-passed` branches, someone can use the `exclude_tag param` to filter out topics and deduce which ones were using a specific hidden tag. This affects any Discourse site using hidden tags in public categories. This issue is patched in version 3.0.1 on the `stable` branch and version 3.1.0.beta2 on the `beta` and `tests-passed` branches. As a workaround, secure any…
Sanitize is an allowlist-based HTML and CSS sanitizer. Versions 5.0.0 and later, prior to 6.0.1, are vulnerable to Cross-site Scripting. When Sanitize is configured with a custom allowlist that allows `noscript` elements, attackers are able to include arbitrary HTML, resulting in XSS (cross-site scripting) or other undesired behavior when that HTML is rendered in a browser. The default configurations do not allow `noscript` elements and are not vulnerable. This issue only affects users who are using a…
wire-server provides back end services for Wire, a team communication and collaboration platform. Prior to version 2022-12-09, every member of a Conversation can remove a Bot from a Conversation due to a missing permissions check. Only Conversation admins should be able to remove Bots. Regular Conversations are not allowed to do so. The issue is fixed in wire-server 2022-12-09 and is already deployed on all Wire managed services. On-premise instances of wire-server need to be updated to 2022-12-09/Chart…

Grafana is an open-source platform for monitoring and observability. Prior to versions 8.5.16 and 9.2.8, malicious user can create a snapshot and arbitrarily choose the `originalUrl` parameter by editing the query, thanks to a web proxy. When another user opens the URL of the snapshot, they will be presented with the regular web interface delivered by the trusted Grafana server. The `Open original dashboard` button no longer points to the to the real original dashboard but to the…
Grafana is an open-source platform for monitoring and observability. Starting with the 8.1 branch and prior to versions 8.5.16, 9.2.10, and 9.3.4, Grafana had a stored XSS vulnerability affecting the core plugin GeoMap. The stored XSS vulnerability was possible because SVG files weren't properly sanitized and allowed arbitrary JavaScript to be executed in the context of the currently authorized user of the Grafana instance. An attacker needs to have the Editor role in order to change a panel to include…
В первой части статьи мы обсуждали разработку самого нижнего слоя СУБД Boson - CachedFileIO. Как упоминалось, статистика такого явления как Locality of Reference говорит о том, что в реальных приложениях ~95% запросов к данным локализованы в 10-15% базы данных. При этом среднее соотношение…
Не так давно мы писали о падении продаж жестких дисков, процессоров и других компонентов и систем. Среди крупнейших вендоров чипов, например — очень сильное падение выручки. Кроме того, продолжают падать и продажи ПК. Неудивительно, что и у производителей смартфонов далеко не все радужно. Точнее — у них все еще хуже. Что случилось, насколько все сложно и каковы причины такой ситуации? Об этом сегодня и поговорим. Читать дальше →
