## [1.2.2] – 2026-10-11
|
||||||
|
|
||||||
|
### Opraveno
|
||||||
|
- **Přečtený chat se dál ukazoval jako nepřečtený.** Zpráva, která přišla do
|
||||||
|
otevřeného chatu, zůstala po návratu do seznamu tučně s odznakem; teď se
|
||||||
|
přečte hned, když je chat na obrazovce (a appka v popředí). Stažení přílohy
|
||||||
|
nebo dodatečné doručení už nevrátí přečtenou zprávu mezi nepřečtené.
|
||||||
|
- Gesto „odpověď tahem“ při zavírání chatu v ladicím buildu padalo na
|
||||||
|
vytvoření animace nad zrušeným prvkem.
|
||||||
|
- Na iPhonu hlásila dlaždice Push v Nastavení chybu (volala UnifiedPush,
|
||||||
|
který existuje jen na Androidu).
|
||||||
|
|
||||||
|
### Změněno
|
||||||
|
- **Nová ikona aplikace:** Š, které se ve spodní části rozpadá do teček.
|
||||||
|
|
||||||
|
## [1.2.1] – 2026-10-09
|
||||||
|
|
||||||
|
### Opraveno
|
||||||
|
- **Hovory se nedaly přijmout.** Příchozí signalizace hovoru se zahazovala dřív,
|
||||||
|
než se dostala k obsluze hovoru; volaný jen „zazvonil“ z budíčku a pak nic.
|
||||||
|
- **Obrazovka hovoru po zavěšení:** avatar a jméno uskakovaly vlevo nahoru.
|
||||||
|
- **Obnova ze 24 slov na novém telefonu** končila nekonečným čekáním — server
|
||||||
|
odmítal už existující identitu. Nové zařízení ji teď převezme podpisem.
|
||||||
|
- **Tichá ztráta zpráv:** úklid mizících zpráv mohl přepsat čerstvě přijatou
|
||||||
|
zprávu; automatický zámek během zpracování zprávy ji mohl nenávratně zahodit;
|
||||||
|
souběžné šifrování pro téhož příjemce dávalo obálky, které druhá strana
|
||||||
|
zahodila. Všechny tři cesty opraveny.
|
||||||
|
- **Velká fronta po delším výpadku** (stovky zpráv) se už neodpojuje v půlce
|
||||||
|
a server ji po osmi pokusech nemaže.
|
||||||
|
- **Nátlakový PIN** otevíral relaci se skutečnou identitou, frází i přístupem ke
|
||||||
|
smazání účtu. Teď je izolovaná: náhodná identita, žádná síť, žádný zásah do
|
||||||
|
klíčů; smazání v ní nechá skutečný účet být.
|
||||||
|
- Zvonění z budíčku bez skutečné nabídky končí po 12 s; server budíčky hovoru
|
||||||
|
omezuje na cíl, takže cizí člověk se znalostí adresy telefon nerozezvoní
|
||||||
|
pořád dokola.
|
||||||
|
- Dodatečné odeslání z fronty neztrácí anketu ani zmínky; budíček při
|
||||||
|
„připojeno“ bez provozu obnoví spojení.
|
||||||
|
|
||||||
|
### Bezpečnost
|
||||||
|
- Hádání PINu: po pěti chybách prodleva 30 s, dál dvojnásobná až 15 minut.
|
||||||
|
- Nátlakový a skutečný PIN se ověřují jednou derivací — čas odemčení neprozradí,
|
||||||
|
který byl zadán.
|
||||||
|
- Biometrie jen biometricky (zámek telefonu appku neodemkne); zabezpečení
|
||||||
|
obrazovky je výchozí zapnuté a po odemčení skutečně platí; na iOS klíče
|
||||||
|
nepřecházejí do iCloud Keychain ani záloh; filtr proti dotykům přes překryvná okna.
|
||||||
|
- Server: doplňování jednorázových klíčů a rotace podepsaných klíčů
|
||||||
|
(`POST /v1/keys`), omezení výdeje jednorázových klíčů na adresu, chyby v logu
|
||||||
|
bez adres push endpointů, připnutí DNS u budíčků, globální strop příloh,
|
||||||
|
limity délek, `/v1/ready`, uvolnění spojení při vypnutí, revize a zdroj
|
||||||
|
v `/v1/server-info`.

## Reporting a vulnerability
|
||||||
|
|
||||||
|
Please report security issues privately — do not open a public issue.
|
||||||
|
|
||||||
|
- E-mail: **security@sepot.cz**
|
||||||
|
- Web form and policy: <https://sepot.cz/zodpovedne-hlaseni>
|
||||||
|
- Machine-readable contact: <https://sepot.cz/.well-known/security.txt>
|
||||||
|
|
||||||
|
You will get an acknowledgement within 72 hours and a status update at least
|
||||||
|
every 14 days until the issue is resolved. We aim to ship a fix within 30 days
|
||||||
|
for issues that affect message confidentiality, authentication, or the relay's
|
||||||
|
metadata guarantees, and we credit reporters in the changelog unless they
|
||||||
|
prefer otherwise.
|
||||||
|
|
||||||
|
## Scope
|
||||||
|
|
||||||
|
- the Flutter client (`app/`), including the Signal protocol integration,
|
||||||
|
local storage (SQLCipher, PIN/biometrics, duress session) and calls;
|
||||||
|
- the relay (`rust/sepot-relay/`): authentication, routing, push wake-ups,
|
||||||
|
attachments, rate limiting, TURN credentials;
|
||||||
|
- the public relay at `relay.sepot.cz` and the website `sepot.cz`.
|
||||||
|
|
||||||
|
Please do not run denial-of-service tests, mass registrations or scans
|
||||||
|
against the public relay; a local instance (`deploy/relay/`) is enough to
|
||||||
|
reproduce almost everything.
|
||||||
|
|
||||||
|
## What the relay can and cannot see
|
||||||
|
|
||||||
|
The threat model is documented in the README: the relay sees routing tokens,
|
||||||
|
message sizes, timing and push tokens, never content or sender identity.
|
||||||
|
Reports that demonstrate the relay learning more than that are the ones we
|
||||||
|
care about most.
