+# [5.3.0-alpha.27](https://github.com/parse-community/parse-server/compare/5.3.0-alpha.26...5.3.0-alpha.27) (2022-09-29)
+
+
+### Bug Fixes
+
+* authentication adapter app ID validation may be circumvented; this fixes a vulnerability that affects configurations which allow users to authenticate using the Parse Server authentication adapter for *Facebook* or *Spotify* and where the server-side authentication adapter configuration `appIds` is set as a string (e.g. `abc`) instead of an array of strings (e.g. `["abc"]`) ([GHSA-r657-33vp-gp22](https://github.com/parse-community/parse-server/security/advisories/GHSA-r657-33vp-gp22)) [skip release] ([#8187](https://github.com/parse-community/parse-server/issues/8187)) ([8c8ec71](https://github.com/parse-community/parse-server/commit/8c8ec715739e0f851338cfed794409ebac66c51b))
+* session object properties can be updated by foreign user; this fixes a security vulnerability in which a foreign user can write to the session object of another user if the session object ID is known; the fix prevents writing to foreign session objects ([GHSA-6w4q-23cf-j9jp](https://github.com/parse-community/parse-server/security/advisories/GHSA-6w4q-23cf-j9jp)) [skip release] ([#8180](https://github.com/parse-community/parse-server/issues/8180)) ([37fed30](https://github.com/parse-community/parse-server/commit/37fed3062ccc3ef1dfd49a9fc53318e72b3e4aff))
+
+### Features
+
+* add option to change the default value of the `Parse.Query.limit()` constraint ([#8152](https://github.com/parse-community/parse-server/issues/8152)) ([0388956](https://github.com/parse-community/parse-server/commit/038895680894984e569dff54bf5c7b31094f3891))
