feat(core): Respect Mask boundaries when reading sentry-label - #6142
Merged
Conversation
…ch breadcrumbs Skip sentry-label when maskAllText is enabled or the touched element is inside a RNSentryReplayMask ancestor, preventing masked text content from leaking into breadcrumbs. Fallback labels (accessibilityLabel, testID) still work. Also skips text extraction from children inside Mask ancestors. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

📜 Description
When Session Replay masking is active,
sentry-labelvalues may contain text derived from component content (viaautoInjectSentryLabelfrom the Babel plugin). This PR ensures those labels are not leaked into touch breadcrumbs when:maskAllTextis enabled (the default whenmobileReplayIntegrationis present) —sentry-labelis skipped entirely.Sentry.Maskboundary —sentry-labeland text extraction from children are both skipped.Fallback labels (
accessibilityLabel,aria-label,testID, customlabelName) continue to work in all cases, since they are developer-provided identifiers rather than user-visible text content.Implementation details
_isMaskAllTextEnabled()from the existing_shouldExtractText()method for reuse.hasAncestorMask()to traverse the fiber tree upward and detectRNSentryReplayMaskancestors.getLabelValue()to accept areadSentryLabelflag that gates thesentry-labellookup.getTouchedComponentInfo()to pass the mask state through.💡 Motivation and Context
Closes#6114
With
autoInjectSentryLabelenabled by default (PR #6141), the Babel plugin injectssentry-labelprops derived from static text content. Without this change, masked text would leak into breadcrumbs viasentry-label, defeating the purpose of replay masking.💚 How did you test it?
