* fix(backend): bump sharp, nodemailer, multer, js-yaml, joi for security fixes Resolves 12 open code-scanning alerts (#589-600): sharp libheif RCE, nodemailer address-parser ReDoS + domain-validation bypasses, multer upload DoS/race conditions, js-yaml parsing DoS, and joi prototype pollution. All patch/minor bumps within the currently used major version. * fix(backend): set multer's fieldArrayIndexLimit to actually close CVE-2026-82333 The advisory is explicit that the 2.3.0 version bump alone doesn't remediate the array-index DoS — an app must also set limits.fieldArrayIndexLimit. Set it on every multer instance, sized to what each route's form actually needs. --------- Co-authored-by: Paul Nothaft <paul@MacStudio-von-Paul.local>
