The company states its realtime servers were unaffected, and all services were secured by 11pm PDT the same day. Firebase found no evidence of compromised passwords but recommends all users change their account passwords and reset their Firebase Secrets from the App Dashboard as a precaution. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Was Firebase affected by the Heartbleed OpenSSL vulnerability? Yes, Firebase's servers managing authentication to the Firebase website were vulnerable to Heartbleed, though the realtime servers were not affected. The vulnerability could have allowed an attacker to intercept authentication credentials in-flight, even though passwords were hashed with bcrypt internally. All Firebase services were secured by 11pm PDT on April 7, 2014, the same day the exploit was addressed. _Track how services responded to critical vulnerabilities like Heartbleed by following security incident coverage on daily.dev._ ### Should I change my Firebase password after the Heartbleed vulnerability? Yes, Firebase recommends all users change their account passwords and reset their Firebase Secrets from the Secrets tab in the App Dashboard. There was no confirmed evidence that passwords or private data were stolen, but because the Heartbleed exploit existed undetected for a long time, credentials could have been silently compromised. _Developers auditing their own OpenSSL exposure after Heartbleed-style incidents can find guidance on daily.dev._ ## Similar posts on daily.dev - [Vulnerabilities](https://daily.dev/posts/vulnerabilities-y7s3glgjt) · Lobsters · 0 upvotes · 0 comments - [FortiBleed leak exposes Fortinet VPN credentials for 73,000 devices.](https://daily.dev/posts/fortibleed-leak-exposes-fortinet-vpn-credentials-for-73-000-devices--gws8xvpp9) · BleepingComputer · 1 upvotes · 0 comments - [Hackers are mass-exploiting a Gravity SMTP flaw to steal API keys from 100,000 WordPress sites](https://daily.dev/posts/hackers-are-mass-exploiting-a-gravity-smtp-flaw-to-steal-api-keys-from-100-000-wordpress-sites-hhj1prnxn) · The Next Web · 0 upvotes · 0 comments --- Tags: [#cryptography](https://daily.dev/tags/cryptography), [#firebase](https://daily.dev/tags/firebase) [View this post on daily.dev](https://daily.dev/posts/openssl-security-update-eq0etumep) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"OpenSSL Security Update","url":"https://daily.dev/posts/openssl-security-update-eq0etumep","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/openssl-security-update-eq0etumep"},"datePublished":"2026-08-23T12:18:21.944Z","dateModified":"2026-08-23T12:28:33.244Z","description":"Firebase confirmed that servers handling authentication to its website were vulnerable to the OpenSSL Heartbleed vulnerability disclosed on April 7, 2014,...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7ed721de96163685d26ab7e314be3ebc?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7ed721de96163685d26ab7e314be3ebc?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Firebase","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Firebase","logo":"https://media.daily.dev/image/upload/s--i395oqZH--/f_auto,q_auto/v1787487448/logos/firebase-blog?_a=BAMAMicg0","url":"https://daily.dev/sources/firebase-blog"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/openssl-security-update-eq0etumep","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"cryptography,firebase","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Firebase","item":"https://daily.dev/sources/firebase-blog"},{"@type":"ListItem","position":3,"name":"OpenSSL Security Update"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/openssl-security-update-eq0etumep#faq","mainEntity":[{"@type":"Question","name":"Was Firebase affected by the Heartbleed OpenSSL vulnerability?","acceptedAnswer":{"@type":"Answer","text":"Yes, Firebase's servers managing authentication to the Firebase website were vulnerable to Heartbleed, though the realtime servers were not affected.
