Siemens ProductCERT security advisories

https://cert-portal.siemens.com/productcert/

Added 2026-09-29: first-party SSA advisories for Siemens OT/ICS (SIMATIC, SCALANCE, SINEC), relevant to civil protection, utilities and building automation in the constituency; CISA ICSA relays arrive later and abridged. RECIPE: `feed https://cert-portal.siemens.com/productcert/rss/advisories.atom 10` (direct; SSA-627195 dated 2026-09-28 at probe), then the SSA HTML or CSAF linked from the item. (2026-09-29 operator-directed setup review) | 2026-10-20 (2026-10-20T0256Z-intel) S1: the atom feed reads direct and lists advisory revisions; the exploitation notice for SSA-580366 is a /news/ post linked only from the advisory page HTML (`url --direct` of the SSA page), both read with `extract`. | 2026-10-31 (S1): `extract` flattens an SSA page affected-product table (product names lost); read the table with `fetch_source.py url --direct <SSA URL>`.
