What is PhotoPrism?

PhotoPrism now lets AI assistants search your photo library over MCP.

PhotoPrism's 29 October release adds OAuth for outside apps and MCP tools so AI assistants can search and browse a library within account permissions, enabled by default and switchable per account. It also adds experimental PostgreSQL support with a database transfer command and an export dialog. September brought new face detection and embedding models plus private and hidden people; October 7 moved classification and NSFW detection to ONNX with GPU support and dropped custom TensorFlow models.

What is SOGo?

SOGo's 5.12 line keeps shipping security fixes, now with mandatory settings attached.

SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made most 2026 releases about security. v5.12.11 in September fixed password reset poisoning and several XSS injections, and made a SOGoPasswordRecoveryBaseURLs setting mandatory when password recovery is on, with a warning that the XSS fix may affect webmail display. v5.12.12 in October fixed another major vulnerability and now verifies LDAP TLS certificates by default.

PhotoPrism vs SOGo: editorial side-by-side

P6.3

PhotoPrism now lets AI assistants search your photo library over MCP.

◆ Current state

PhotoPrism's 29 October release adds OAuth for outside apps and MCP tools so AI assistants can search and browse a library within account permissions, enabled by default and switchable per account. It also adds experimental PostgreSQL support with a database transfer command and an export dialog. September brought new face detection and embedding models plus private and hidden people; October 7 moved classification and NSFW detection to ONNX with GPU support and dropped custom TensorFlow models.

◆ Where it's heading

The vision stack is now fully ONNX and GPU-capable, and the library itself is becoming something other tools can query. PostgreSQL support breaks the long MariaDB/SQLite limit for larger installs.

◆ Prediction

PostgreSQL leaving experimental status and MCP gaining more than read-only search are the likely next steps, given both arrived in first form here.

2.5

SOGo's 5.12 line keeps shipping security fixes, now with mandatory settings attached.

◆ Current state

SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made most 2026 releases about security. v5.12.11 in September fixed password reset poisoning and several XSS injections, and made a SOGoPasswordRecoveryBaseURLs setting mandatory when password recovery is on, with a warning that the XSS fix may affect webmail display. v5.12.12 in October fixed another major vulnerability and now verifies LDAP TLS certificates by default.

◆ Where it's heading

Fixes are increasingly arriving with secure defaults that break lax configurations, first password recovery URLs and then LDAP certificate checks. Feature work has been absent since 5.12.4 a year ago.

◆ Prediction

Further 5.12.x security releases are likely; operators should expect more defaults that require configuration changes.
