CVE-2025-58480

California residents now have a real tool against the data broker industry.

The state has launched DROP, a single portal to demand deletion of your personal data from 500+ registered data brokers in one request, for free.

To start: https://consumer.drop.privacy.ca.gov/

@sassdawe Wow congrats!

@addison It's obvious you have a lot to say :) I think the presentation was also very good (using sokoban as a model is spot on!), it's just that internalizing new perspectives takes time, and I think we were better off getting multiple highlights of ideas instead of working through any one of them during the time given - we have the recording, slides, etc. to dig deeper as we like.

@addison Thanks for the great talk, definitely the most thought provoking one for me from this CCC! Have to watch it like 3 more times to get all the details though 😅

@hanno As another datapoint, MOTW bypasses worth CVE's at MS (e.g. CVE-2025-24061). It's not the same ofc. as an automatic control is bypassed in such cases, but at the same time users could choose to bypass the control after a warning (which the CVE also bypasses).

@murb @bert_hubert @signalapp Great, that can be a checkbox then! I'm also sure that support/M.W. didn't have to deal with as many angry Europeans if the us-east-1 only affected users over the pond :)

@filippo @freddy @hanno I'll save this thread under "even your vendor doesn't approve CVSS" for future reference

@embedding_shapes @rickoooooo nix-shell works though, leaving you with tasks that are too complex for that but don't justify a container. Now I'm sure that can be a deal-breaker too, but it's worth keeping in mind that there is room for ad-hoc tasks.

@rislandr I had an account, forgot the pw, couldn't reregister the last time I tried...

@hanno I'm bringing this up exactly because when CVSS will be assigned it will either show 0.0 or some really weird non-sense. The former would be likely a better, but still misleading scenario,. My bet is on MITRE publishing some non-sense though.

@hanno Not saying it's not a vulnerability but I think you won't be able to score this with CVSS that would make CVE registration weird.

Now those gpg.fail people made me find similar vulns elsewhere (console control character injection). By "elsewhere" I mean... my own code.
Opinions wanted: should "input can inject console output with ansi and control chars" always be considered a vuln/CVE?
(I'll fix it in any case, I'm just wondering if I should do all the "security release/advisory/request CVE/..." stuff.)

@bert_hubert @signalapp This is exactly why I think sharing some actual unmet requirements would be a good idea.

(FTR I was told they also used GCP as a fallback which apparently didn't work too well)

Thinking back to last year I remembered the us-east-1 outage, how it affected Signal and how some of the users freaked out that they have to rely on US hyperscalers.

Wouldn't it be useful if @signalapp (and maybe similar providers) published their infra requirements with little crosses and ticks, so alternative providers could aim for "good enough for Signal" service levels?
