# Security digest: May 4, 2025

1 editorial brief.

## Take stock

- Check exposure: TeleMessage TM SGNL: Open Heap Dump Endpoint Leaked Messages . Organizations that used TeleMessage archiving apps (TM SGNL and its WhatsApp, Telegram and WeChat variants) before May 2025, and any team running Spring Boot Actuator on internet-facing services.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

- **Check exposure** [TeleMessage TM SGNL: Open Heap Dump Endpoint Leaked Messages](https://erroneo.us/security/briefs/telemessage-tm-sgnl-heapdump-cve-2025-48927/index.md): There is nothing to patch: the flaws were in TeleMessage's hosted archive, suspended in May 2025, so former customers should treat archived messages and credentials as exposed and Spring Boot teams should confirm /heapdump is not public.

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
