Beskrivelse:
Claudio "Sverx" har identificeret en svaghed i Opera, som kan udnyttes af ondsindede personer til at lokke brugere til at besøge et ondsindet website ved obfuskere URLs i statusbaren.

Problemet er at browseren ikke viser den korrekte URL i statusbaren hvis et billede med en "title" attribut hyperlinkes, men benytter en form til at specificere URLen. Dette kan forårsage at en bruger følger et link til der umiddelbart peger på et site der haves tillid til men faktisk åbner et ondsindet site.

Svagheden er relateret til
SA17565

Eksempel:
<form action="[ondsindet site]">
<a href="[site]"><input type="image" src="[billede]" title="[site]"></a>
</form>

Svagheden er bekræftet i version 8.5. Andre versioner er også berørte.
