+# Synapse 1.120.1 (2024-12-03)
+
+This patch release fixes multiple security vulnerabilities, some affecting all prior versions of Synapse. Server administrators are encouraged to update Synapse as soon as possible. We are not aware of these vulnerabilities being exploited in the wild.
+
+Administrators who are unable to update Synapse may use the workarounds described in the linked GitHub Security Advisory below.
+
+### Security advisory
+
+The following issues are fixed in 1.120.1.
+
+- [GHSA-rfq8-j7rh-8hf2](https://github.com/element-hq/synapse/security/advisories/GHSA-rfq8-j7rh-8hf2) / [CVE-2024-52805](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-52805): **Unsupported content types can lead to memory exhaustion**
+
+  Synapse instances which have a high `max_upload_size` and which don't have a reverse proxy in front of them that would otherwise limit upload size are affected.
+
+  Fixed by [4b7154c58501b4bf5e1c2d6c11ebef96529f2fdf](https://github.com/element-hq/synapse/commit/4b7154c58501b4bf5e1c2d6c11ebef96529f2fdf).
+
+- [GHSA-f3r3-h2mq-hx2h](https://github.com/element-hq/synapse/security/advisories/GHSA-f3r3-h2mq-hx2h) / [CVE-2024-52815](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-52815): **Malicious invites via federation can break a user's sync**
+
+  Fixed by [d82e1ed357b7ee21dff83d06cba7a67840cfd464](https://github.com/element-hq/synapse/commit/d82e1ed357b7ee21dff83d06cba7a67840cfd464).
+
+- [GHSA-vp6v-whfm-rv3g](https://github.com/element-hq/synapse/security/advisories/GHSA-vp6v-whfm-rv3g) / [CVE-2024-53863](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-53863): **Synapse can be forced to thumbnail unexpected file formats, invoking potentially untrustworthy decoders**
+
+  Synapse instances can disable dynamic thumbnailing by setting `dynamic_thumbnails` to `false` in the configuration file.
+
+  Fixed by [b64a4e5fbbbf119b6c65aedf0d999b4237d55503](https://github.com/element-hq/synapse/commit/b64a4e5fbbbf119b6c65aedf0d999b4237d55503).

+
+  Non-state events, like messages, are unaffected.
+
+  Synapse instances can disable the Sliding Sync feature by setting `experimental_features.msc3575_enabled` to `false` in the configuration file.
