| CVE-2022-0217 | It was discovered that an internal Prosody library to load XML based on libexpat does not properly restrict the XML features allowed in parsed XML data. Given suitable attacker input, this results in expansion of recursive entity references from DTDs (CWE-776). In addition, depending on the libexpat version used, it may also allow injections using XML External Entity References (CWE-611). | [email protected] | 7.5 | 4.40% | 2022-08-26 | 2024-11-21 |
| CVE-2021-37601 | muc.lib.lua in Prosody 0.11.0 through 0.11.9 allows remote attackers to obtain sensitive information (list of admins, members, owners, and banned entities of a Multi-User chat room) in some common configurations. | [email protected] | 7.5 | 2.33% | 2021-07-30 | 2024-11-21 |
| CVE-2021-32921 | An issue was discovered in Prosody before 0.11.9. It does not use a constant-time algorithm for comparing certain secret strings when running under Lua 5.2 or later. This can potentially be used in a timing attack to reveal the contents of secret strings to an attacker. | [email protected] | 5.9 | 1.60% | 2021-05-13 | 2024-11-21 |
| CVE-2021-32920 | Prosody before 0.11.9 allows Uncontrolled CPU Consumption via a flood of SSL/TLS renegotiation requests. | [email protected] | 7.5 | 2.26% | 2021-05-13 | 2024-11-21 |
| CVE-2021-32919 | An issue was discovered in Prosody before 0.11.9. The undocumented dialback_without_dialback option in mod_dialback enables an experimental feature for server-to-server authentication. It does not correctly authenticate remote server certificates, allowing a remote server to impersonate another server (when this option is enabled). | [email protected] | 7.5 | 1.40% | 2021-05-13 | 2024-11-21 |
| CVE-2021-32918 | An issue was discovered in Prosody before 0.11.9. Default settings are susceptible to remote unauthenticated denial-of-service (DoS) attacks via memory exhaustion when running under Lua 5.2 or Lua 5.3. | [email protected] | 7.5 | 2.11% | 2021-05-13 | 2024-11-21 |
| CVE-2021-32917 | An issue was discovered in Prosody before 0.11.9. The proxy65 component allows open access by default, even if neither of the users has an XMPP account on the local server, allowing unrestricted use of the server's bandwidth. | [email protected] | 5.3 | 2.17% | 2021-05-13 | 2024-11-21 |
| CVE-2020-8086 | The mod_auth_ldap and mod_auth_ldap2 Community Modules through 2020-01-27 for Prosody incompletely verify the XMPP address passed to the is_admin() function. This grants remote entities admin-only functionality if their username matches the username of a local admin. | [email protected] | 9.8 | 1.56% | 2020-01-28 | 2024-11-21 |
| CVE-2018-10847 | prosody before versions 0.10.2, 0.9.14 is vulnerable to an Authentication Bypass.

A user may authenticate to XMPP host A and migrate their authenticated session to XMPP host B of the same Prosody instance. | [email protected] | 4.2 | 1.66% | 2018-07-30 | 2024-11-21 |
| CVE-2017-18265 | Prosody before 0.10.0 allows remote attackers to cause a denial of service (application crash), related to an incompatibility with certain versions of the LuaSocket library, such as the lua-socket package from Debian stretch.

| CVE-2016-0756 | The generate_dialback function in the mod_dialback module in Prosody before 0.9.10 does not properly separate fields when generating dialback keys, which allows remote attackers to spoof XMPP network domains via a crafted stream id and domain name that is included in the target domain as a suffix. | [email protected] | 5.3 | 2.05% | 2016-01-29 | 2026-05-06 |
| CVE-2016-1232 | The mod_dialback module in Prosody before 0.9.9 does not properly generate random values for the secret token for server-to-server dialback authentication, which makes it easier for attackers to spoof servers via a brute force attack. | [email protected] | 7.5 | 2.18% | 2016-01-12 | 2026-05-06 |
| CVE-2016-1231 | Directory traversal vulnerability in the HTTP file-serving module (mod_http_files) in Prosody 0.9.x before 0.9.9 allows remote attackers to read arbitrary files via a .. (dot dot) in an unspecified path. | [email protected] | 5.9 | 2.87% | 2016-01-12 | 2026-05-06 |
| CVE-2014-2745 | Prosody before 0.9.4 does not properly restrict the processing of compressed XML elements, which allows remote attackers to cause a denial of service (resource consumption) via a crafted XMPP stream, aka an "xmppbomb" attack, related to core/portmanager.lua and util/xmppstream.lua. | [email protected] | 7.8 | 3.14% | 2014-04-11 | 2026-05-06 |
| CVE-2014-2744 | plugins/mod_compression.lua in (1) Prosody before 0.9.4 and (2) Lightwitch Metronome through 3.4 negotiates stream compression while a session is unauthenticated, which allows remote attackers to cause a denial of service (resource consumption) via compressed XML elements in an XMPP stream, aka an "xmppbomb" attack. | [email protected] | 7.8 | 3.31% | 2014-04-11 | 2026-05-06 |
| CVE-2011-2532 | The json.decode function in util/json.lua in Prosody 0.8.x before 0.8.1 might allow remote attackers to cause a denial of service (infinite loop) via invalid JSON data, as demonstrated by truncated data. | [email protected] | 5.0 | 1.45% | 2011-06-22 | 2026-04-29 |
