About REDFLAG DESK
The flag tells you how urgent it is
REDFLAG DESK is security news for people who build and run websites. In Formula 1, marshals warn drivers of danger with flags. In the same way, we show how urgent each vulnerability or breach is for you with four flags: RED, DOUBLE YELLOW, YELLOW and BLUE.
The four flags
DOUBLE YELLOW FLAG
Double yellow: great danger, be ready to stop
Patch promptly
Severe impact with a public exploit or reported (unconfirmed) exploitation, including RED candidates under review.
YELLOW FLAG
Yellow flag: caution, slow down
Review and plan
Conditional updates, investigation or recovery follow-ups, and regulatory deadlines.
BLUE FLAG
Blue flag: be aware
For awareness
Policy, research, industry trends and guides that need no immediate technical action.
RED only by fixed rules
An AI suggestion alone never yields RED. We require a CISA KEV listing or a programmatic match of an exploitation statement in a vendor or government primary source.
How we use AI
We use Claude (Anthropic) to triage sources and draft bilingual summaries. Versions are filled from data; unknown facts are marked as unconfirmed.
Corrections and updates
Flag changes, new fixed versions, wider impact and corrections are added as new revisions. Earlier revisions are kept.
